10 Small Details That Could Ruin Upcoming Comic Book Movies

6. Iron Man Overshadowing The Movie - Captain America 3

Everybody has been doing double backflips ever since Marvel announced that Robert Downey Jr. would be joining the likes of Chris Evans for the upcoming Captain America 3, but is anybody worried that the movie is likely to become another vehicle for Robert Downey Jr. to overshadow his fellow cast mates? Granted, he needs to be involved if the film intends to kick start the infamous Civil War storyline, but to what sacrifice? After all, Captain America 3 is a Captain America movie, and Captain America should remain the focus of the picture despite the fact that it will feature a plot involving Iron Man. But Downey Jr. is inarguably the most popular Marvel superhero, and it'll be hard to feature him in a way that doesn't turn attention away from the - let's face it - less interesting Steve Rogers. Small as this may seem, Marvel have their work cut out for them.
