Captain America Pictures

In this week's releases, two friends get physical in Friends with Benefits, and an underdog becomes a superhero in Captain America. Thanks to the many movies based on comic books, and the release of No Strings Attached earlier this year, some of you may feel like you already know what to expect from these new films. To get a better idea of how these two movies differ from those that came before them, take a look at photos from each.
