Hostage thriller Argo has bested eight rivals including Steven Spielberg's Lincoln to claim the best picture Oscar, despite Ben Affleck's controversial omission from the best director shortlist.
Argo is just the fourth film in Academy Awards history to take out the top prize at the Oscars without its director also being nominated.
While Spielberg left empty-handed, Lincoln's Daniel Day-Lewis made Oscar history, becoming the first person to take home three best actor trophies after winning for his role as America's 16th president.
Jennifer Lawrence picked up the coveted best actress statue, while Anne Hathaway and Christoph Waltz won the supporting categories and Ang Lee picked up best director.
Look back at how the action unfolded at Hollywood's Dolby Theatre. All times AEDT.
4.00pm: And that's all she wrote, folks. You can look back on all today's winners here.
|Best picture: Argo|
The movie is based on the true story of the CIA rescue from Islamic revolutionary Tehran of six US diplomats who pretended to be producing a fake film.
Accepting the award, director Ben Affleck gives a nod to Iran in his acceptance speech.
I want to thank Canada, I want to thank our friends in Iran, who live under terrible circumstances.
I want to thank you my wife, who I don't normally associate with Iran.
There are eight great films that have as much right to be up here as we do.
You have to work harder than you think you can. You can't hold grudges. And it doesn't matter how you get knocked down in life ... all that matters is you got to get back up.
Argo is just the fourth film ever to win best picture without also having a best director nomination. It follows Wings, Grand Hotel and Driving Miss Daisy.
3.54pm: In a surprise move, Michelle Obama helps introduce the nominees for best picture: Amour, Argo, Beasts of the Southern Wild, Django Unchained, Les Miserables, Life of Pi, Lincoln, Silver Linings Playbook and Zero Dark Thirty.
I want to congratulate all the nominees on their tremendous work.
They reminded us that we can overcome any obstacle if we dig deep enough.
Every day through engagement in the arts our children learn .. to dream just a little bigger.

|Best actor: Daniel Day-Lewis for Lincoln|
Day-Lewis just made history, becoming the first person to win three best actor Oscars. He also won in 1989 for My Left Foot and in 2007 for There Will Be Blood.
It's a strange thing because three years ago, before we decided to do a straight swap, I had been committed to play Margaret Thatcher.
And Meryl was Steven's first choice for Lincoln - I'd like to see that version.
Steve didn't have to persuade me to do it. I had to persuade him that if I was going to do it that Lincoln shouldn't be musical.
He thanks Steven Spielberg and makes reference to Lincoln's impact on history, and wraps up by thanking his mum.
For my mother - thank you so much.
His win means Hugh Jackman misses out - ending Australia's chances of taking home a gong.
3.46pm: Best actor time. Up for the award are Bradley Cooper for Silver Linings Playbook, Daniel Day-Lewis for Lincoln, Hugh Jackman for Les Miserables, Joaquin Phoenix for The Master, and Denzel Washington for Flight.
|Best actress - Jennifer Lawrence for Silver Linings Playbook |
Every Oscar winner's worst nightmare comes true as Lawrence trips on the stairs before accepting her Oscar.
You guys are just standing up because you feel bad that I fell, and that's really embarrassing.
This is nuts. Thank you to the women this year - you were so amazing.
3.41pm: Time for the best leading actress award. It's between Jessica Chastain for Zero Dark Thirty, Jennifer Lawrence for Silver Linings Playbook, Emmanuelle Riva for Amour, Quvenzhane Wallis for Beasts of the Southern Wild, and Naomi Watts for The Impossible.
|Best director - Ang Lee for Life of Pi|
Thank you movie God. I really need to share this with all 3,000 who worked with me on the Life of Pi.=
I want to thank you for believing in this story.
Thank you to Yann Martel for writing this incredible book.
Lee thanks his wife of 30 years, and also thanks his lawyer and agent, saying "I have to do that".
Steven Spielberg has now lost best director twice to Lee.
3.32pm: Time for the coveted best director gong. It's between Michael Haneke for Amour, Benh Zeitlin for Beasts of the Southern Wild, Ang Lee for Life of Pi, Steven Spielberg for Lincoln, and David O. Russell for Silver Linings Playbook.

|Best original screenplay - Quentin Tarantino for Django Unchained |
Tarantino, who's wearing a leather tie, accepts the award from Dustin Hoffman and his neighbour, Charlize Theron.
I actually think if people are knowing about my movies 50 years from now, it's going to be about the characters I create.
I have to cast the right people to make those characters come alive and live for a long time. And boy, this time, did I do it!
It's such an honour to get it this year because in both the original and the adapted categories, the writing is so great. This will be the writer's year, man. Peace out.
|Best adapted screenplay - Chris Terrio for Argo|
|Best original song - Adele Adkins and Paul Epworth for Skyfall |
Adele gives us the first on-stage tears of the night, but just manages to hold it together.
"You're all amazing," she tells the crowd.
The win marks the first Bond-related Oscar win since Thunderball picked up a trophy for visual effects in 1965. It's fitting given Hollywood is celebrating 007's 50th anniversary this year.
|Best original score - Mychael Danna for Life of Pi |
2.57pm: Steel yourselves: George Clooney introduces the In Memoriam section.
A video montage pays tribute to those who shone both in front of the camera and behind the scenes, including Jack Klugman, Michael Clarke Duncan, Marvin Hamlisch, Tony Scott and Nora Ephron.
Barbra Streisand then takes the stage to sing Memories, .
|Best production design - Rick Carter and Jim Erickson for Lincoln|
2.35pm: Adele time! The songstress is on stage to perform her Bond hit Skyfall.
She is good, but not great - and the crowd might just agree, as they didn't give her a standing ovation.
|Best film editing - William Goldenberg for Argo|
|Best supporting actress - Anne Hathaway for Les Miserables|
She dreamed a dream, and accepting her Oscar, says: "It came true".
She thanks Les Miserables director Tom Hooper, the film's cast and her friends and family.
I must thank you Hugh Jackman - Hugh you're the best.
My husband, by far and away the greatest moment of my life was the one where you walked into it. I love you so much.
Here's hoping that one day not too soon, the misfortunes of Fantine will only be found in stories, and never in real life.
Hathaway's win means Australian Jacki Weaver has missed out on the award for her part in the film Silver Linings Playbook.
2.21pm: Best supporting actress time. It's between Amy Adams for The Master, Sally Field for Lincoln, Anne Hathaway for Les Miserables, Helen Hunt for The Sessions, and Jacki Weaver for Silver Linings Playbook.
2.18pm: Here's a recap of the winners so far:
Best supporting actor: Christoph Waltz for Django Unchained
Best foreign language film: Amour
Best animated feature: Brave
Best cinematography: Life of Pi
Best costume design: Anna Karenina
Best documentary feature: Searching for Sugar Man
Best documentary short: Inocente
Best make-up: Les Miserables
Best short animated film: Paperman
Best sound mixing: Les Miserables
Best sound editing: Zero Dark Thirty and Skyfall
|Best sound editing - It's a tie! Paul N.J. Ottosson for Zero Dark Thirty, and Per Hallberg and Karen Baker Landers for Skyfall|
A tie is very rare, but it has happened before.
The first tie in 1932, when Wallace Beery and Frederic March both won best actor.
In 1968 Katharine Hepburn and Barbra Streisand shared the best actress award.
There were also ties in 1949 for documentary short subject, in 1986 for documentary feature and 1994 for live action short.
|Best sound mixing - Andy Nelson, Mark Paterson and Simon Hayes for Les Miserables|
2.10pm: Here's a snap of MacFarlane backstage.
2.01pm: The cast of Les Miserables is on now, singing the classics from the musical.

1.54pm: John Travolta dances onto the stage to introduce a tribute to musical films.
Catherine Zeta-Jones nails All That Jazz before Jennifer Hudson absolutely belts out And I Am Telling You.
Enjoy it while it lasts, because Russell Crowe is coming soon.

He thanks the Academy for the honour, and pays tribute to his wife:
You are the centre of my life.
|Best documentary feature - Malik Bendjelloul and Simon Chinn for Searching for Sugar Man|
The Jaws theme makes a return to cut their acceptance speech off.
1.41pm: Seth MacFarlane makes his most inappropriate joke so far, saying Daniel Day-Lewis is not the first actor to get inside Abraham Lincoln's head.
The actor who really got inside Lincoln's head was John Wilkes Booth.
Really, 150 years and still too soon?
Booth assassinated Lincoln at Ford's Theatre in 1865. Lots of people on Twitter are saying it was in poor taste, but I think it's surprising the Family Guy creator didn't cross the taste line sooner.
|Best short documentary - Sean Fine and Andrea Nix Fine for Inocente|
Fine pays tribute to one of the subjects in the doco:
We want to thank this young lady who was homeless a year ago, and now she's standing before you.

1.31pm: Jessica Chastain .

Shirley Bassey is in the house now, singing Goldfinger in a tribute to 007. She gets a standing ovation from the crowd after a strong finish.
|Best make-up and hairstyling - Lisa Westcott and Julie Dartnell for Les Miserables|
The win means Australian Rick Findlater misses out on an Oscar for his work on The Hobbit: An Unexpected Journey.
|Best costume design - Jacqueline Durran for Anna Karenina|
|Best visual effects - Bill Westenhofer, Guillaume Rocheron, Erik-Jan De Boer and Donald R. Elliott for Life of Pi|
For the first time so far, music is brought on to end the acceptance speech. It's the Jaws theme song.
Their win means Australian Dave Clayton, who had been nominated for his work on The Hobbit: An Unexpected Journey, misses out.
|Best cinematography - Claudio Miranda for Life of Pi|
1.06pm: MacFarlane jokes that The Avengers was the most popular movie of the year, "which is why it's only nominated once".
1.01pm: Here's a look back at how the first ever Oscars unfolded:
About 270 people attended the first Academy Awards ceremony on May 16, 1929.
Tickets costs $5 each and the ceremony lasted 15 minutes.
American Janet Gaynor won best actress for Sunrise and Seventh Heaven, both from 1927, and Street Angel from 1928.
The best actor award went to Swiss-born Emil Jannings for The Last Command and The Way of All Flesh.
Wings won best picture and musical The Jazz Singer received a special award as the "pioneering outstanding talking picture".
It was ruled ineligible for best picture because the Academy thought it would be unfair to let sound films compete with silents.
In total 15 awards were given out, with the winners decided months earlier.
The next year, the Academy decided to keep the results secret until the ceremony.
Best animated feature: Mark Andrews and Brenda Chapman for Brave
Best animated short film - John Kahrs for Paperman
12.55pm: You can peek inside the Oscars program here.
Best supporting actor - Christoph Waltz for Django Unchained
Waltz pays tribute to his character in the film - a German dentist turned bounty hunter.
My unlimited gratitude goes to Dr King Shultz - and the creator of his awe-inspiring world, Quentin Tarantino.
You can watch Tarantino narrate a scene featuring Waltz here.
12.48pm: Best supporting actor time. It's between Alan Arkin for Argo, Robert De Niro for Silver Linings Playbook, Philip Seymour Hoffman for The Master, Tommy Lee Jones for Lincoln, and Christoph Waltz for Django Unchained.
Historian William Loren Katz is hoping Tommy Lee Jones wins for his turn as Congressman Thaddeus Stevens.
Writing in the Huffington Post, he looks at how Hollywood has painted Stevens in the past and expresses hope that Spielberg's movie will shine a spotlight on Stevens. It's an interesting perspective.
12.31pm: In the words of the Academy... ready Seth go!

Family Guy creator Seth MacFarlane takes to the stage, saying his quest is to make Tommy Lee Jones laugh.
He gets big laughs for touching on the Academy's perceived snub of Argo director Ben Affleck, saying the story is "so top secret the film's director is unknown to the Academy".
Ben, they know they screwed it up.
He turns the act into a running joke about whether he will be deemed the worst ever Oscars host, and William Shatner arrives as Captain Kirk to save MacFarlane's broadcast.
MacFarlane launches into a song listing the actresses who have gone topless in films. "We saw your boobs," he sings.
Shatner hits back that actresses want to be honoured, not mocked.
MacFarlane is joined on stage by Charlize Theron and Channing Tatum, and he croons a version of The Way You Look Tonight.
Joseph Gordon-Levitt and Daniel Radcliffe then join MacFarlane on the stage for another musical number. But Shatner says it's still not enough to evade the "mediocre host" tag, so MacFarlane launches into an Oscar-themed version of Be Our Guest.
The host gets big cheers from the crowd, but it feels a little too safe and self-aware for my liking.
Like many, I expected MacFarlane to ruffle a few Tinseltown feathers and push some boundaries with his humour, and it's not happening just yet.
12.30pm: The stars are taking their seats for the Oscars ceremony.

12.05pm: Poor Seth MacFarlane. It seems many people were expecting actor Seth Rogan to host.
Rogan didn't do much to discourage that view, tweeting that he was "so psyched" to take to the stage.
12.02pm: Twilight actress Kristen Stewart is on the red carpet with crutches. .
While today's event celebrates the best in cinema, Stewart yesterday received a less honourable award in the form of a Razzie.
11.55am: Jacki Weaver is speaking to Channel Nine's Richard Wilkins, joking she is now so posh that she has a stylist.
She says going to bed with Robert DeNiro in Silver Linings Playbook "wasn't bad at all - and I got paid to do it".

I think they're lucky to rub shoulders with me.
11.48am: Last year a Twitter account was made for Angelina Jolie's leg after the actress caused a stir with her revealing split dress (and awkward posing).

I can't sit down and feel like my organs are being pushed out of my body.

Field says the actor would send her text messages in character as Lincoln:

Gordon-Levitt reveals he got a letter from Day-Lewis that closely mimics Lincoln's penmanship:
He actually signed it as both - it was D/A. It's one of my most prized possessions.

10.51am: Argo's Bryan Cranston, who's also known for his role in Breaking Bad, tells E! that director Ben Affleck is more nervous than excited.
Regardless of how much experience you have in front of the microphone, when it comes to that time when you're being honoured, there's butterflies.
He also spills on his entertainment expectations for the evening:
We're hoping for a wardrobe malfunction, at least on someone, that's always exciting.
10.46am: Australian star Jacki Weaver, who is up for the best supporting actress gong for Silver Linings Playbook, looks gorgeous in a red gown which she has teamed with $2 million worth of diamonds.
She also reveals it took her almost four hours to "get my face on".
"What beautiful eyes you have," she jokes to E! presenter Ryan Seacrest.
10.45am: Did you know... Daniel Day-Lewis originally turned down the lead in Lincoln, but reconsidered after Steven Spielberg insisted he couldn't make the film without him. Smart move, Daniel.

She also spills on why she chose her nude-toned gown, which is winning over fashion critics:
It's a very 'Happy Birthday, Mr President' kind of dress. It remind me of old Hollywood glamour.

10.10am: Rachael MacFarlane, the sister of host Seth, reveals he has been rehearsing for five months.

10.07am: Quvenzhane Wallis, the young Beasts of the Southern Wild star, has arrived on the red carpet, as has her best actress rival Jessica Chastain.

I went to rehearsals last night and I caught a glimpse of Seth MacFarlane who's hosting it and it took me back to 2011 when I hosted, and I was like - being nominated is a walk in the park.
It also helps being in a category where there's Daniel Day-Lewis, you don't even have to worry about an acceptance speech.
9.55am: Ben Affleck is on the red carpet now. He was snubbed by the Academy in the best director category but his flick Argo is up for best picture.

Fennell says Ben Affleck's Argo will "almost definitely" beat Steven Spielberg's presidential drama Lincoln in the best picture stakes.
Although Lincoln was the early frontrunner, Argo has dominated Hollywood's awards season so far, so I'm inclined to agree.
Check out Fennell's other tips:
