YMMV: Source Code
- Actor Allusion: Jake Gyllenhaal at one point says "Everything's going to be OK." It isn't.
- Adam Westing: Comedian Rusell Peters basically plays an expy of himself.
- Hey, It's That Voice!: Colter's father is played by none other than Scott Bakula. As the film was tagged by its creators as Groundhog Day meets Quantum Leap, this is probably not coincidental.
- Special Effects Failure / Uncanny Valley: When Colter is rolling on the ground after jumping off the train, it's a little too obvious that it's a CGI stand-in.
- Deliberately invoked when Colter realizes his body is dead.
- The Woobie: Colter. He's trapped in a dark box, not knowing what is happening to him, and is forced to live his own death and witness countless others over and over again without being allowed to die properly.
