Benedict Cumberbatch was already caught up in the Oscar "party pandemonium" before he went on to photobomb U2 on the red carpet.
The British actor halted a pre-show interview as a huge roar went up for another star arrival at the Dolby Theater and declared: "This place is crazy."
12 Years A Slave star Lupita Nyong'o, who went on to claim the best supporting actress award, and her director, Steve McQueen, also gave their pre-show thoughts, along with Philomena star Steve Coogan.
Twitter has responded with a host of spoofs following Oscar host Ellen DeGeneres' record-breaking celebrity selfie.
Steve McQueen's 12 Years a Slave was named Best Picture at the 86th Academy Awards, but who else was honoured with an Oscar?
The 86th Academy Awards take place on Sunday which means the red carpet has been rolled out and the nominees are preparing their speeches.
