- Adaptation Displacement: For some viewers, the film overshadows the Philip K. Dick source story.
- Hilarious in Hindsight: Jennings watching a highlight reel of the baseball season he lost while working on the secret project. The team he's distressed about because they lost in the playoffs? The Boston Red Sox, of which Ben Affleck is a big fan of in Real Life. It's also a case of Time Marches On as the Boston Red Sox actually won their first world series in 86 years the year after the film was made.
- Narm: It might have gone better had the referenced scene (in which Jennings states that he believes he can change his future) not been deleted:
James Rethrick: Still think you can change your fate, Mike? I AM THE FUTURE MIKE!
- It appears that this scene was reinstated in the DVD release.
- Retroactive Recognition: Henry is one of the FBI agents chasing Jennings.
- That actor was also in another film which dealt with manipulating time to change the future - in Terminator 2: Judgement Day he created Artificial Intelligence, of all things. No fate but what we make indeed.
- Apparently Dexter is in the FBI as well.
- To start the movie, Lily Rush is one of the executives Jennings does a project for.
