David Weaver from Lights Remote Action writes: There are many easy comparisons one can throw out there for the inspirations that Source Code is seemingly derived from. I caught glimpses of 12 Monkeys mixed with a large chunk of Groundhog Day and what is quickly becoming a popular quote for anything dealing with multiple realities, it has a lot of Inception in there as well to spice things up a bit. Is it fair to label a film with comparisons like those? Perhaps not but I can't help it if those were the films that kept popping into my head as I sat in that theater and experienced Duncan Jones creation. And let's face it, if a film makes me think of three amazing movies like those in a positive manner then that is very much a good thing in my opinion.The important perspective to keep though is to not hold the film up to any standards that those other amazing pieces of work have set. Source Code deserves to be looked at based on its own merits.
