As you’ve heard, the cast of Batman v Superman: Dawn of Justice is teaming up with celebrity charity site Omaze for very cool prizes. The grand prize winner will get to ride in the Batmobile and then take a photo with Ben Affleck at the NYC premiere, fly with Henry Cavill in a helicopter, and photobomb the cast with Jesse Eisenberg on the red carpet. Head on over to Omaze to donate and learn more about this great contest.

We’ve seen Henry Cavill talk to kids, and Jesse Eisenberg troll fans, and now Omaze has released a video starring Ben Affleck. Watch as he surprises fans on the Warner Bros. Studio Tour with the Batmobile in the video above!
