Trivia: Check out the nurse that wakes Kristen up at the school infirmary. It is Robert Englund, out of his Freddy make-up. After Kristen wakes up, it is a different person.
Trivia: Paul Thomas Anderson, who directed Tom Cruise in Magnolia, has a cameo on the train. It is reported that he is so hard to find that Anderson himself does not know where he appears.
Trivia: At the ranger's office when the security guard was stealing the medical supplies, you see a cameo of M. Night Shamalayan in the reflection of the glass.
Trivia: The cat that Gene Hackman has is the same cat that was in Men in Black, and similarly, the cat is put into a bag in this film just like in MIB.
Trivia: When the alien's hand comes out of the coal grate for Morgan, if you look closely you will see that the hand was already through the grate and the alien was using its colour changing abilities to hide. So if you look very closely you will that that the hand comes UP from the grate and not through it, and if you look VERY carefully you can see the outline of the hand even before Morgen says "What?"
Trivia: The message "For Sasha" which appears just before the end credits is a dedication to director Nick Cassavetes' daughter.
Trivia: In the party scene at XXX's house after he pulls the stunt with the Corvette, Joshua Todd, the ex-lead singer of Buckcherry, makes a cameo appearance - he never turns around, but you can see the suicide king of hearts tattoo on his back.
Trivia: Closely listen to the TV playing in the background, when Mathew Broderick comes home from school, before all his trouble starts with the Feds. The local news is on, and is saying "a fire broke out in a prophylactic recycling factory."
Trivia: The minigun that the Terminator (Arnie) uses in the Cyberdyne scene was so heavy that Arnold Schwarzenegger was the only person on set strong enough to lift it.
Suggested correction: In one of the special features on the Blu-ray version, director James Cameron can be seen holding and shooting the minigun, while saying: "Arnold's gonna love this."
Trivia: M3gan's scenes were done with an actual person wearing a mask (with some CGI being used to animate the eyes and face.) The girl's name is Amie Donald, and she is an accomplished gymnast and dancer, and in the scenes with the hallway dance and running on all fours were not special effects, Amie actually did those moves.
Trivia: As the family is leaving home in their car, a neighbor asks that they also take her daughter, Ellie. ELE, pronounced the same as the name, stands for Extinction Level Event.
Trivia: Nicolas Cage has no speaking lines throughout the entire movie.
Trivia: This is the first non-English language film to win the Academy Award for Best Picture.
Trivia: Peter Capaldi, the new Doctor Who for 2014, is listed in the credits as W.H.O. Doctor. Just a fun coincidence, as the roles are too far apart to have been planned, but worth a look.
Trivia: The "Bride in Black" is played by a man wearing women's clothing. This was done so that something would feel "off" about the image of the ghost. At the time, the character was intended to be female. However, when the creators later reused the character for the sequel and added in a backstory, they worked the fact that the character was played by a male as part of his backstory - it actually is a man who masqueraded as a woman as a disguise to lure in victims.
Trivia: The scene in which the blue car does several flips on the grass would later be used in the first season of the TV show "The Fall Guy" starring Lee Majors.
Trivia: In the scene where Ripcord and Duke are in the transport and Ripcord pats Heavy Duty on the back and gets his arm twisted as a result, Ripcord makes a crack about Heavy Duty having a "Kung Fu Grip". This refers to some of the earliest G.I. Joe's action figures who were advertised to have the Kung Fu Grip.
Trivia: When Agent Strahm is in his head box trap screaming, there is a lot of flash-cutting, including a shot of an outtake of the actor smiling with a towel in the cube and staff around him. Happens exactly at 9:52:370 into the movie, or frame 14203. VERY fast and easy to miss.
Trivia: Reese's introduction isn't the only thing that stays the same about the character between movies. Here he uses his preferred weapon - a sawed-off shotgun. Marcus isn't keen on having a gun aimed at him though, so he snatches it out of Reese's hands, then teaches him a trick to keep that from happening - fashioning a safety strap. Reese puts that same trick to use after he steals a police shotgun in The Terminator. (00:49:55 - 01:49:58)
