This couple really love DC comic books, especially Batman, and chose to have a super hero themed wedding with each guest choosing what to come as. The bride and groom, I think, are The Joker and Harley Quinn. And who better to conduct the ceremony than Batman himself?
Guests included Iron Man, Wolverine, Mystique, Bane, Wonder Woman, Riddle and one even chose to be Super Mario - who says he's not a super hero? LOL...
