Opening on April 1 is Summit Entertainment’s sci-fi thriller Source Code.  Directed by Duncan Jones (who previously made the incredible Moon), the film stars Jake Gyllenhaal, Michelle Monaghan, Vera Farmiga, and Jeffrey Wright.   If you aren’t familiar with the plot, Gyllenhaal stars as a soldier who wakes up in the body of a stranger on a Chicago commuter train and "learns he’s part of a government experiment called the ‘Source Code,’ a program that enables him to cross over into another man’s identity in the last 8 minutes of his life.”  Watch the trailer here.Since I'm pretty sure I'm under embargo…hypothetically speaking…if I were to have seen an early screening, I might be able to tell you that I thought Source Code was really good.  For now that's all you'll get out of me.  Anyway, for a taste of the film, watch a clip after the jump:Here's all our previous coverage on Source Code.
