There's a lot of early buzz about Jake's upcoming film, Prince of Persia: The Sands of Time, largely due to pics of his muscular physique circulating on the web. Fans will have to wait until May of 2010 to see all that hotness up close in a movie theatre. Sigh. It should be a great summer adventure yarn.

The film also has a good supporting cast which includes Ben Kingsley, Gemma Arterton. Alfred Molina and Toby Kebbell.

Metro reports:
Jake Gyllenhaal has revealed he packed on the muscle for his role in new film Prince of Persia: The Sands of Time. "I over-prepared myself because I never knew how much they were going to ask me to do, so I just made sure I'd be hopefully able to do anything," Jake told Entertainment Tonight, adding that he had gained five pounds of muscle for the role of the 6th century prince. "I guess I've gotten buff," he said. "There's a lot acrobatics in the movie - a lot of running up walls, and jumping on things, so it requires muscularity, but it requires a lot of aerobic ability too." However, Jake doesn't plan on keeping his buff bod for long after the London film shoot wraps. "It's going to turn into fat and I'm going to be happy," he laughed.
