One of the reasons why Iron Man 2 didn't beat The Dark Knight's box office record was probably because the film wasn't available in 3D formats – making it the first huge blockbuster of 2010 to not come equipped with a 3D version. Speaking with the LA Times, Marvel's Kevin Feige admits they tossed around the idea of presenting Iron Man 2 in 3D, but the schedule just wouldn't allow it – and after Clash of the Titans was criticized for rushing its 3D conversion, Paramount and Marvel backed off the idea of converting Iron Man 2 as well.
