There's a lot of buzz surrounding Jake Gyllenhaal's new movie role.

After all, the 30-year-old actor shaved his head for End of Watch, a police drama costarring Michael Pena. Though filming doesn't begin until July, Gyllenhaal and Pena, 35, shot promos for the movie in L.A. last week.

This isn't the first time Gyllenhaal has lost his locks for a role; in 2005, he shaved his head to play Marine Anthony Swofford in Jarhead.
