I watched the two movies: "Deja Vu" and "Source Code." In this essay, I will compare the similarities and differences in the two movie plots. Both are about men who find themselves in a situation where they must travel back to a specific window of time to attempt to prevent a catastrophic event. Both, in the process of completing their mission, fell in love with a woman fated to be killed if they failed. So, these stories seem very similar, however, there are many differences within the two movies which I will explore in the following paragraphs. In the Source Code Colter Stevens is sent to an eight minute time period to find the bomber on a train. He would be sent back to this eight minute period as an entirely different person (being injected into this person's consciousness). Every time at the end of the eight minute mark he would die and be sent back to a pod. Inside the pod he talks to Goodwin who talks with Stevens when in his alternate reality state. Colter Stevens' real body consists of only the upper half, due to an accident on a mission in Afghanistan which made him the perfect candidate for the job. So in this movie the way he travels time is by superimposing his consciousness in time. In deja vu Doug Carlin an ATF agent solves the terrorist attack (A bomb was set off on a boat full of children, women and soldiers who had gotten home from war) by getting the opportunity to join a secret team that has new technology called "Snow White  allowing the controller to go exactly 4 ½ days in the past allowing the controller to capture 360 degree everywhere 4 ½ days in the past. After they witness the murder of Doug Carlin's old friend that also worked for ATF, Doug goes back in time to fix the past and change the future by sending himself through a portal of some sort. So they're similar in that they both have set periods they go back in time to, however, their methods are very different. Source Code and Deja Vu b
