Plenty of this year's nominees aren't exactly what you could call unpredictable. There's Meryl, and Leo, and Jennifer, and no major upsets are expected on the night.
But what about the less usual suspects? Digital Spy takes a look back at eight Oscar-winners you may have forgotten about...
The Twelfth Doctor himself took home a statuette from the Academy in 1995, for writing and directing short film Franz Kafka's It's A Wonderful Life. Not to be confused with Frank Capra's actual It's A Wonderful Life, the absurdist short follows Kafka (played by Richard E Grant) in the throes of writer's block while attempting to write his masterpiece The Metamorphosis, and it tied for Best Live Action Short Film with Peggy Rajski's Trevor.
Few will have forgotten the fuss that erupted when Rolling Stone named Eminem "The King of Hip-Hop' three years ago, but he'd already had a more significant genre honour bestowed upon him a decade earlier, when 8 Mile's 'Lose Yourself' became the first rap track ever to receive the Best Original Song Oscar. The win was so unexpected that when it was announced, Mr Mathers himself was at home, asleep in front of cartoons with his daughter. Aw.
Yep. The Dean from Community. Totally won an Oscar, and not even for acting – Rash co-wrote the script for George Clooney-starrer The Descendants, alongside Nat Faxon and director Alexander Payne. Rash and Faxon reunited to write last year's similarly bittersweet indie comedy The Way Way Back, a gem which unfortunately didn't have a high enough profile to make this year's shortlist.
Collins has won plenty of awards in his time, but Disney's 1999 Tarzan is unlikely to be the first place your mind goes to when you're pondering what for. He penned all of the soundtrack's songs (alongside Mark Mancina on scoring duties) and 'You'll Be in My Heart' nabbed the big prize on Oscar night. The soundtrack also earned a Grammy and a Golden Globe, which still left Collins a fair way from earning an EGOT (Emmy, Grammy, Oscar and Tony). He does have the OGGG, for what that's worth.
Despite being snubbed by the Academy this year for her compelling comeback performance in The Butler, the reason might simply have been that it's only been two years since they gave her the Jean Hersholt Humanitarian Award. This special honour is bestowed periodically – Angelina Jolie will be this year's recipient – to celebrate outstanding contributions to humanitarian causes. It's given out at the separate Governors Awards rather than the main ceremony, which is one reason many people may be unaware of Oprah's status as an Oscar winner.
It's really, really difficult to look back beyond the fog of unrelenting bilge that has become Cage's career, particularly now that National Treasure 3 is reportedly in the works. But back in the day, Cage the respectable actor won the Best Actor gong for his performance as a suicidal alcoholic in Leaving Las Vegas. Could he pull a Matthew McConaughey-style career renaissance out of the bag in time for next year's awards?
Goggins is now best known for his role as career criminal Boyd Crowder in FX drama Justified, for which he's been Emmy-nominated. But back in 2001, Goggins co-won the Best Live Action Short Film award for Ray McKinnon's "farm comedy" The Accountant, in which he played second lead.
Okay. We'll admit, this one is a stretch, since technically Danny Dyer wasn't the recipient of the 2005 Oscar for Best Live Action Short (yep, that old chestnut again). Fish Tank director Andrea Arnold won it for Wasp, a 30-minute drama which starred Dyer as an ex-boyfriend trying to rekindle the flame with Natalie Press's single mum. The very fact that Danny Dyer was involved in Oscar-winning work justifies this inclusion.
