* HeyItsThatPlace: The law firm Dean works for is in the same building used as the headquarters in ''Series/{{JAG}}''.
* LifeImitatesArt: The current and ongoing controversies surrounding federally-endorsed NSA surveillance conducted on the greater American public certainly seem to echo the points addressed by the film.
* TechnologyMarchesOn: For a tech thriller, it's certainly strange in retrospect to see characters making such extensive use of ZIP discs.
