This year will be a big one at theaters with “Batman v Superman,” “Captain America: Civil War,” and “X-Men: Apocalypse.”

These films are anticipated not just for the stars taking on legendary comic book roles like Jared Leto as The Joker or Gal Gadot in Wonder Woman’s first big screen appearance, but also because of the huge action sequences.

While the movies draw crowds, they wouldn’t be possible without the dedicated and highly-trained stunt people who train in gymnastics, martial arts, and parkour to prepare for roles.

From the doubles for Ben Affleck to Chris Evans, these are the people who take the death-defying risks while making our favorite stars look good.
