It appears Jake Gyllenhaal is continuing to branch out from the typical dramatic roles most moviegoers expect from him.  The Oscar-nominee will topline next summer's "Prince of Persia: The Sands of Time" and now he's in negotiations to star in the Sci-Fi thriller "Source Code."

Variety reports the Summit Entertainment release will find Gyllenhaal playing a soldier who wakes up in the body of an unknown commuter and in a "Groundhog Day" scenario, is forced to relive a deadly train bombing until he can determine who is responsible for it. Duncan Jones, who received raves for his indie Sci-Fi flick "Moon," is on board to direct.

At one point, Topher Grace was set to star in the feature, but dropped out when the film was put into turnaround at Universal Studios.

Gyllenhaal isn't abandoning his bread and butter, however.  He'll appear alongside Tobey Maguire and Natalie Portman in Jim Sheridan's drama "Brothers" next month and is currently filming Ed Zwick's "Love and Other Drugs" with Anne Hathaway and Hank Azaria.  The 28-year-old previous dived into the science-fiction genre with "The Day After Tomorrow" and "Donnie Darko."

Jones is also working on "Mute" which should be his next film after "Source."

Production is currently set to begin early next year.
