For Jake Gyllenhaal, playing Prince Dastan in Jerry Bruckheimer’s epic Prince of Persia: Sands of Time, due May 28, 2010, was a chance to get into some serious action. (Paparazzi photos of Gyllenhaal on-set have appeared previously, but this is the first official shot of him in character.) “I’m tired of taking myself so seriously,” says the actor, who found himself sword-fighting, climbing walls, and jumping off of buildings as part of the prince’s quest to find an enchanted dagger and turn back time. “It’s nice when a stuntman turns to you and is like, ‘Actors don’t normally do this.'”

For a sweet, glossy copy of the photo and other exclusive first looks, be sure to pick up this week’s issue of Entertainment Weekly, on newstands now.
