Captain America closes out a Summer where some more secondary super-heroes in Thor, X-Men, and Green Lantern. While Thor made $445.7 million globally X-Men: First Class has taken in a respectable $346.8 million, its no where near the $585.2 million take of Iron Man and $622.1 million for Iron Man 2, leading some executives to believe that consumers may be tiring of super hero flicks.

The real litmus test will be The Dark Knight Rises coming July 20 next year and Sony’s Spider-Man reboot also next July, in addition to the Superman film Man of Steel in 2013. Depending on how well those films do, it might seal the fate of super-hero movies.
