Source Code is a 2011 U.S. science fiction action thriller film directed by Duncan Jones and written by Ben Ripley. It stars Jake Gyllenhaal as U.S. Army Captain Colter Stevens, who is sent into an eight-minute digital re-creation of a real-life train explosion, tasked with determining the identity of the terrorist who bombed it. Michelle Monaghan, Vera Farmiga, and Jeffrey Wright play ing roles.

Military helicopter pilot Colter Stevens (Jake Gyllenhaal) finds himself on a train, talking to Christina (Michelle Monaghan), who thinks he is someone else. After some minutes of confusing conversation, the train is involved in an explosion and crash, and Stevens wakes up in a capsule in conversation over a video link with Captain Goodwin (Vera Farmiga). It turns out that Stevens is involved in the Source Code project which enables him to be sent back into target Sean Fentress to relive 8 minutes leading up to the terrorist explosion, in order to find out who the terrorist is in order to prevent a second atrocity.

Source Code is not a clichéd mediocre action blockbuster. The movie avoids being predictable and wants to be smart and mind-bending. Duncan Jones isn't the kind of director who cares about the action. By the way this is his first action movie but he's smart for not making super cool unrealistic action scenes. He cares about the story. The movie has many intriguing subplots that are not easy to figure out. The movie wanted to be as smart as possible.

The performances were great. Jake Gyllenhaal made the whole game exciting. Michelle Monaghan shows her role's innocence. Vera Farmiga is obviously good here. Jeffery Wright is the best among the four. Chris Bacon's music score sounds old fashioned and I liked it. The effects aren't really that great but it doesn't matter. The script is indeed smart. The movie also has a heart.

Overall, Source Code is a fun movie - think Quantum Leap meets Groundhog Day. Another original sci-fi movie in the list, a nail biting thriller which will keep you on the edge of your seat throughout the movie. This gets straight to the point without wasting any time for setting up the story. Though it's an original sci-fi movie, it doesn't go into the technicality nor makes it too complex. It's simple and to the point. If you want to watch a fast paced thriller, you can consider this for sure.
