In what is possibly the best video we've seen all year, here's the moment when Benedict Cumberbatch photobombed U2 at this year's Oscars.

If you didn't already know what the Sherlock star did, allow us to refresh your memory. At this year's Academy Awards, as various A-list celebrities walked down the red carpet greeting fans, journalists, and posing for pictures, Cumberbatch decided to photobomb U2, jumping up behind them as they had their photo taken.

The event was well-documented on the night with plenty of people amused by his silly behaviour. While there were many photos of the moment, the video footage has just emerged showing the Star Trek star jumping up and down behind Bono and the gang.

Even funnier is that the video shows how Cumberbatch initially spots the band and clearly makes the decision to go and carry out his joke.

This isn't the first time he's been the subject of a viral video. Back in December, Cumberbatch appeared on Jimmy Kimmel Live, for which he read out the lyrics to R. Kelly's Genius. Unsurprisingly, the video has had over 2.5 million views, of which we are responsible for roughly half (we pressed replay A LOT).

Recently, Cumberbatch was interviewed for T, the New York Times Style magazine, in which he said he thought his most famous character, Sherlock Holmes, was an "absolute b**tard".

The actor said: "I always make it clear that people who become obsessed with him or the idea of him — he’d destroy you."
