It seems the two stars of Batman v Superman: Dawn of Justice aren’t just battling it out on screen, but also behind the scenes in the form of silly pranks.

Affleck shared a funny video to his Facebook and Instagram account on Thursday revealing some of the hi-jinx the cast of the Zack Snyder movie got up to.

In it, Affleck, 43, appears to have decorated Cavill’s trailer full of the film’s posters, joking in his post: “Henry, I’m flattered. I didn’t know you were such a fan! We know #WhoWillWin.”

Over to you, Cavill.

Batman v Superman: Dawn of Justice hits theaters March 25.
