* ActorAllusion:
** Kicked off Creator/NicolasCage's "Beige Volvo" trilogy. And then of course Connery's lines about being a [[Film/JamesBond British agent]]. Roger Ebert 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.]]
* HeyItsThatGuy:
** One of the Marines is [[Series/{{Scrubs}} Perry Cox]]. Another is [[Series/{{House}} Detective Tritter]], another is [[ThePractice Gene Young]], another is [[Series/TheCloser Detective Sanchez]], and another is [[Film/BlackHawkDown Sergeant Galentine]]. Goodspeed's girlfriend is Sam Marquez from ''Series/LasVegas'', the leader of the [=SEALs=] is [[TheTerminator Kyle Reese]], and Ed Harris. Just...Ed Harris.
** One reviewer said of Ed Harris "the dude has a glare that would give Clint Eastwood chills." Probably why he was so damn unnerving in ''Film/EnemyAtTheGates''.
** You should see the [[http://www.youtube.com/watch?v=BYN6t5xt0ps outtakes]]. It's MethodActing, but '''GODDAMN, is Harris scary.'''
** Shep is Jack's best friend in ''Film/{{Titanic}}''.
** The Film/{{Candyman}} is now a Marine!
** Turns out that before becoming White House Chief of Staff, [[{{TheWestWing}} Leo McGarry]] was Director of the FBI.
** Super-obscure (because his face is masked), but one of the pilots of the fighter jets in the climax is played by Creator/JimCaviezel.
** [[DeadPresidents Cleon]] is Gunnery Sergeant Crisp.
** [[Series/TwentyFour Xander]] [[Series/{{Nikita}} Berkeley]] appears uncredited early on as one of Goodspeed's coworkers.
* ThrowItIn: Much of NicolasCage's dialogue was ad-libbed (including the "Zeus's butthole" line, which Creator/MichaelBay wanted to cut but Cage insisted on having).
* WhatCouldHaveBeen: Goodspeed was originally going to be played by, of all people, '''Creator/ArnoldSchwarzenegger'''. He turned it down because he didn't like the script.
