These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
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.
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.
