Director Matthew Vaughn is a huge comic book fan, as his upcoming Kick-Ass adaptation hopes to prove. However, Vaughn has left more superhero movies than he's made, having abandoned both Thor and X-Men: The Last Stand.
But that doesn't mean that Vaughn isn't ready for more. Vaughn told MTV about two projects he's hoping to direct:
I grew up watching superhero films, so I want to make superhero films. I was desperate to do Iron Man about 8 years ago, and everyone was like, "Iron Man, no one will go watch that." Cut to now, and it's a huge hit. [I'd] love to do The Avengers. And Superman ... I think it would be great to reinvent Superman.
Of course, Jon Favreau directed Iron Man, and he's also been discussed as the potential director for The Avengers. In fact, Favreau feels that The Avengers might keep the Iron Man series from falling into predictability:
...The Avengers might be the thing that helps rescue us from the inevitable sequel slump that you get into, because you're throwing everything on its ear. It might be a failed experiment or it might be something wonderful, but it allows you to add complexity in an organic way where you're culminating with something bigger, as opposed to trying to play out and not repeat the same story over and over again.
Vaughn might have a better chance at the next Superman, though James McTeigue has been strongly rumored to be directing the project.
