As the heroes prepare to assemble, we look back on previous films
'Captain America: The First Avenger'
'nuff said: The fan favorite comes to the screen this month, as Chris Evans steps into the role as the WWII-era hero who will eventually wake up in modern times as an Avenger. Surprises are surely in store, but we know Cap will appear in next year's "The Avengers" and that Howard Stark (Tony's dad) appears in the film. Synergy!
Worldwide box office: TBD
