The Jake Gyllenhaal who appeared at Saturday's WonderCon in San Francisco was in a markedly better mood than the Oscar nominated actor this journalist met on the set of "Prince of Persia."  Visiting the London production in December of 2008, Gyllenhaal was incredibly serious and almost dazed when sitting down to discuss the movie adaptation of the popular video game with HitFix.  On this afternoon, however, Gyllenhaal was the smiling, self-deprecating, friendly and genuine actor the press and industry is used to working with (basically the polar opposite of his sister Maggie). 

Whether Gyllenhaal is feeling the pressure of his first broad action role is unclear, but his excitement regarding his next two projects, Ed Zwick's "Love and Other Drugs" and Duncan Jones "Source Code," was extremely evident. Gyllenhaal is shooting Jones' follow up to the critically acclaimed "Moon" and he was clearly chomping at the bit to reveal more details about the flick. 

To enjoy Mr. Gyllenhaal's enthusiam, you can watch the exclusive interview embedded on this page or for a larger version, click here.

"Prince of Persia: The Sands of Time" opens nationwide on May 28.
