Turns out none of the lie-detection or lying skills transferred across from Matt Damon playing the role of Bourne, but he does seem like he loves a good parlour game.

Jason Bourne himself got to play one of the tamer games in Fallon's repertoire last night but maybe he should have picked 'Frozen Blackjack' like Michael Fassbender and just put up with some icy balls because he really was useless when it came to 'Box of Lies'.

But look, he was having a great time just being there. We're glad he got the day out.
