James Corden as Matt Damon’s Jason Bourne stunt double? Yes, you read that correctly. The Late Late Show host made it through, but not without a few bumps, bruises, a punch to the face, well.. you’ll see.

Corden says the idea was hatched when he ran into Damon while he was out clothes-shopping and asked him to be a guest on the show.  Damon agreed, according to Corden, but only if Corden would return the favor and be in Damon’s next Bourne movie. It looks like Corden may have misjudged the role Damon had in mind.
