** Kicked off Creator/NicolasCage's "Beige Volvo" trilogy. And then of course Creator/SeanConnery's lines about being a [[Film/JamesBond British agent]]. Creator/RogerEbert described the latter as "an in-joke the entire world gets."
** And [[Film/TheAbyss this isn't the first film where Michael Biehn plays the leader of a Navy SEAL team.]]
** Creator/WilliamForsythe says that he knows all about the cloak and dagger stories, when he is talking to Womack about J. Edgar Hoover. Forsythe was in ''Cloak & Dagger'' (1984).
* ActorInspiredElement: It was Creator/NicolasCage's idea that his character would not swear; his euphemisms include "gee whiz."
* CastTheExpert: Some of the Navy SEALs in the film were played by real Navy SEALS.
* CastingGag: Creator/SeanConnery as a former British agent.
* ExecutiveMeddling: Bay was getting quite an amount of studio interference, until Connery [[DefiedTrope told them to just let Bay make the movie the way he wanted]], if they wanted Connery to stay with the film.
* InMemoriam: The film was dedicated to Don Simpson, who died during production.
* MissingTrailerScene: In the trailer, several shots appear to show Goodspeed firing an XM177 assault rifle. While Goodspeed does acquire an XM177 during the course of the film, he never actually fires it.
* ThrowItIn: Much of Creator/NicolasCage's dialogue was ad-libbed (including the "Zeus's butthole" line, which Creator/MichaelBay wanted to cut but Cage insisted on having).
** Creator/ArnoldSchwarzenegger was offered the Mason role, but at the time the script was only eighty pages "with a lot of handwriting and scribbles, and it didn't seem fully baked". In a Reddit AMA, he stated he regrets not taking the role.
** Creator/TonyScott was originally supposed to direct but turned it down to direct ''The Fan''.
