In Iron Man 2 Sam Rockwell plays Justin Hammer, the wealthy industrialist who just doesn't quite have the panache to be a Tony Stark. But not all is lost-- Rockwell is getting his chance to play a superhero after all. In fact, he's playing Batman. And Justin Long is his Robin. No, seriously.

According to Production Weekly, Rockwell and Long will be reprising their roles as the crimefighting duo for another take on "Robin's Big Speed Date," which originated in 2007 as a short directed by James Duffy (you can watch it embedded below). The new take on the same material will be part of the giant anthology now known simply as Untitled Comedy-- it's the one that will feature Hugh Jackman sporting testicles on his chin and Chloe Moretz as a girl getting her first period, among presumably many other juvenile and hilarious set-ups.

Rockwell and Long will be joined in the new "Robin's Big Speed Date" by John Hodgman as The Penguin, Leslie Bibb as Wonder Woman and Josh Hamilton, also part of the original short playing an ordinary guy, will play Superman. The entire concept might not work for a feature film, but as one short in a whole lineup of crazy shorts, it's hard to imagine much of anything that would be funnier.
