Bruce Willis is strapping on John McClane's tank-top-and-machine-gun combo once again for a Valetine's Day 2013 release of the next Die Hard sequel, A Good Day to Die Hard. Though Willis is on board, there is an important part that the film still needs to cast: John McClane Jr. Rumors are swirling that the studio is testing actors to play McClane's son in the film, which will follow McClane as he and his boy fight a threat in Russia together. Casting is still up in the air at this point, though a few names have been tossed around, like Breaking Bad's Aaron Paul, Paul Dano, and Ben Foster. But it's time for you to play casting director: who would you like to see as Willis's son in the action franchise?
