Trivia: The face of The Hulk is a computer generated image of Erik Bana, Jennifer Connelly, and director Ang Lee combined into one.
Trivia: Amongst the taunts that the Nightrider shouts to the police on the CB is a verse of the song "Rocker" by AC/DC.
Trivia: When Eric first goes back to his apartment, right after he returns from the grave, it is raining inside the apartment and his movements look an awful lot like the movements he just made in the rainy alleyway. [Not really a mistake, but worth noticing - the filmmakers were forced to re-use some shots after Brandon Lee's death.]
Trivia: The filmmakers originally had an ending in which Alex grabs the cable that lies on Clear's car, Alex catches fire and dies. Then Clear gets her baby and Carter survives. The test audience didn't like this, so the filmmakers shot another ending in which Alex is decapitated by a crashing police helicopter. But again, the test audience didn't like the fact that Alex dies, so they shot the finish with the billboard, which took 6 days to film and cost nearly $2,000,000.
Trivia: R. Lee Ermey actually wrote all of Gunny Hartman's dialog himself. Ermey was involved in a serious car accident right before shooting, so Kubrick invited Ermey to come stay at his house in England to recover. While recovering Ermey read the script over and over, and he remarked that the Drill Instructor's dialog that was in the script was obviously the work of a screenwriter with a cliche imagination who obviously had no idea what boot camp was really like. So Kubrick allowed Ermey to re-write all of the dialog himself.
Trivia: While Steve McQueen performed most of his own stunts, the only stunt he didn't perform was the 60 foot jump over the Austrian-Swiss border fence. The jump was performed by stuntman Bud Ekins, who later doubled for McQueen in "Bullitt."
Trivia: Paramount Studios essentially rented a US submarine to be in the movie. The USS Houston (SSN 713) played the USS Dallas and the surface scenes were filmed off of Long Beach, CA and Port Angelas, WA. Two crewmembers off the Houston were actually given very small speaking parts in the movie.
Trivia: Stay after the credits. There's an additional scene where John goes to visit Chas' grave and leaves a lighter, then as he's walking away you see Chas with wings and he flies up into the sky. (01:54:40)
Trivia: Mel Gibson references the Three Stooges several times in the film. In real life, Gibson is a big Stooges fan, and in 2000, he produced the biographical TV movie "The Three Stooges."
Trivia: The personal bios of the characters are handed out in the order that they die in.
Trivia: One should really stay to the very end of the credits, as Johnny Depp (Mort) sings an amusing little tune.

Trivia: Actress Mila Kunis was actually recommended by Natalie Portman for the part of Lily.
Trivia: The movie was originally scripted with a male lead and Tom Cruise was approached to play the title character. Ultimately, he backed out and the script was rewritten with a female lead and Angelina Jolie took the role.
Trivia: During filming, George Clooney paid a visit to his friends on the set of "ER" wearing the batsuit.
Trivia: When the planes bombard the desert ruins, the explosion, which holds the Guinness record, took 8 months to be made, more than principal filming took! Also, the planes used while filming in fact bombarded the set, as explosives detonated for the massive explosion. Seems Michael Bay enjoyed the high budget of this film.
Trivia: When John turns on the magnetic field, the equipment he uses to turn up the power is the throttle of the Saitek X45 with a Cyberdyne plate over the base. (01:22:55)
