The Sci-Fi Shuffle is back, and no "thinky" movies this time (except we overthink it anyway) - it's the 2011 film "Source Code"! We talk time loop movies, infinite Jakes and and energy drinks. It's the movie that dares to ask the question: would you rather be blown up on a train or pretend to be a high school teacher for the rest of your life? One of cinema's classic conundrums!
