VIDEO: Superheroes Beating Super Stars at Box Office

Star-driven movies have been box office busts this summer, with most of them fading from theaters before hitting their expected blockbuster status.  The latest Superman, "Man of Steel", had the biggest June opening ever.  "Man of Steel" enjoyed this year's second-biggest debut weekend, behind only "Iron Man 3" -- another superhero franchise film.

Among the Hollywood star films with disappointing ticket sales: Will Smith's "After Earth", Tom Cruise's "Oblivion", Sylvester Stallone's "Bullet to the Head", and Arnold Schwarzenegger's "The Last Stand".
