Jake Gyllenhaal at the "Source Code" premiere video

When Jake Gyllenhaal stepped onto the red carpet at the Cinerama Dome for Monday night's premiere of his new sci-fi thriller "Source Code," a girl across Sunset Boulevard who had shimmied up a tow zone sign shrieked, "Jaaaaaake! I wanna have your baby!" Gyllenhaal, flanked by "Source Code" co-stars Vera Farmiga, Jeffrey Wright and Michelle Monaghan, was the man of the hour. In the film, he plays Air Force Capt. Colter Stevens, who is on a top-secret mission to save Chicago from a dirty bomb by going back in time -- via a parallel universe called the Source Code -- to discover who blew up a Chicago commuter train (the first in a series of planned terrorist attacks). As a result, he must relive the same eight minutes leading up to the bombing over and over again.
"I found it really freeing," Gyllenhaal said of the experience of acting inside a deeply warped space/time continuum. "A lot of times you stay within the structures and confines of the reality that you're aware of, and in this your imagination could run wild." He also said that one of the fights in the movie was a real fight. "Duncan [Jones, the director] said, 'Just go for it'. The fight he's talking about takes place on a train platform and it does look pretty raw". Source: latimesblogs.latimes.com
