* ActorAllusion: DenzelWashington's character is named Frank Barnes; in ''AmericanGangster'', a prior film of his (which just so happens to have been made by Tony Scott's brother Creator/{{Ridley|Scott}}), there is a character named Nicky Barnes, and Denzel played Frank Lucas.
* HeyItsThatGuy:
** [[MyNameIsEarl Randy Hickey]] was fully responsible for the whole mishap, with a little help from his good friend [[Film/{{Cloverfield}} Hud]].
** Of course, [[Film/StarTrek Captain Kirk]] had to save the day.
** [[Series/OnceUponATime Cinderella]] is his estranged wife.
** [[Film/TheBookOfEli Eli]] helping probably didn't hurt.
** [[Film/{{Dogma}} The Golgothan shit monster ]] caused the incident.
** [[Series/{{Fringe}} Sam Weiss]] the Bowling Guy is the FRA inspector.
** [[{{Film/Transformers}} Sam Witwicky's dad]] is the BadBoss.
** [[Series/PersonOfInterest Lionel Fusco]] is that guy with headphones.
* ProductionPosse: Tony Scott and DenzelWashington had previously worked together on ''CrimsonTide'', ''Film/ManOnFire'', ''Film/DejaVu'' and {{the remake}} of ''[[TheTakingOfPelhamOneTwoThree The Taking of Pelham 1-2-3]]''.
* [[PromotedFanboy Promoted Fangirl]]: Rosario Dawson has made mention of her Trekkie roots, and here she is assisting Captain Kirk in a rescue mission.
* ShoutOut: To SilverStreak - an AWVR official named Gene Devereaux is interviewed at one point. GeneWilder starred in Silver Streak, and the villain was named Roger Devereaux.
* While there are RealPlaceBackground spots in the movie where NoCommunitiesWereHarmed, they all have fake names to cover up their actual real-world locals. The only place in the movie that gets any semblance of realism is the mention of Horseshoe Curve (a railfan's wet dream in most cases) and the giant bridge / curve which is physically located in Bellaire, Ohio but in the movie gets a huge leap to Scranton, Pa (according to map, renamed to Stranton for the movie)
** The reason for the leap was made more clear in commentary for the movie reviews; apparently the director happened to be a railfan also and figured Scranton, Pa where the real life Railroad Museum Steam Town U.S.A. exists would be a perfect place to end it.
