With six Marvel superhero films on the horizon, it's safe to say that studio head Kevin Feige is a pretty busy guy -- even more so lately as Iron Man 3 approaches its May 3 debut.

"We're entering that finishing crunch time where the days of the week have no meaning because you're working all seven of them," Feige told Variety in a recent interview.

And among the upcoming Phase 2 slate, one of the more intriguing pics is Captain America: The Winter Soldier , which, as Feige notes, will be drastically different from any past Marvel movie."There's an opportunity to graft almost sub-genres onto them," said Feige of their superhero brand. "Our first Captain America film was a World War II picture, and the next is a political thriller. They all have their own textures and patinas, and that's what is exciting about it."Captain America 2 stars Chris Evans, with Joe and Anthony Russo directing. The film opens April 4, 2014.
