If you told me four years ago that a movie like The Avengers would be made, I would have laughed in your face. To create a film based on a team like that would require a lot of time and would need major financing. So instead of just making a straight-up film based on The Avengers, Marvel went forward with focusing on the individuals who make up The Avengers, eventually leading up to the team-up.

Warner tried to go with just with a straight-up film based on the Justice League, but with problems with financing and the writer’s strike, the film was put on hold for a couple of years. Seeing the successful formula that Marvel has created, WB might want to replicate that with Batman entering a reboot phase after The Dark Knight Rises.
