Tom Cruise was on top of the world in London Sunday night — or at least on top of the BFI Imax cinema.

On Sunday afternoon, the Mission: Impossible actor was photographed on the roof of the BFI IMAX building in London. It’s unclear how exactly the actor scaled up the roof, but we’ve confirmed with sources close to Cruise that it was indeed him.

The four-time Oscar nominee was in the city as a recipient of the BFI's highest honor, the award of BFI Fellowship. To celebrate the occasion, Cruise took the stage at BFI Southbank for a conversation moderated by DJ and presenter Edith Bowman.
