To date, Christopher Nolan’s The Dark Knight still stands as the highest-grossing solo superhero film at the domestic box office, but when it comes to worldwide grosses, Gotham’s protector has been trumped by the international appeal of Iron Man 3. So when it comes to standalone superhero movies, the popularity contest boils down to DC’s Batman and Marvel’s Iron Man.
The fact that the respective alter-egos of Bruce Wayne and Tony Stark are the biggest box office draws is a curious one, especially considering the striking similarities between the two characters. Much like Wayne, Stark is a billionaire mogul with a brilliant mind for science who uses his ample resources to take down the criminal element and neutralize threats. But who would win if these two heroes got on each other’s bad sides?
