Ryan Phillippe is Sweating Bullets

Ryan Phillippe works up a sweat in the California sun while doing a running stairs cardio workout out in the Hollywood Hills on Tuesday morning.

The 33-year-old actor looked in great shape as he worked out solo and shirtless.

Later this year, Ryan will star in the fantasy drama, Franklyn (UK only). The movie follows four intertwining stories, three of which takes place in contemporary London and the fourth takes place in Meanwhile City, a parallel fantasy environment. In Meanwhile City, atheist vigilante Jonathan Preest (Phillippe) fights against the various religious presences. Ultimately, his path crosses with three others (Eva Green, Sam Riley, Bernard Hill) from London.
