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)
Trivia: When Marcus Wright, Kyle Reese, and Star leave Los Angeles, they make their way up the hill up to Griffith Park. This is an homage to Terminator 1 because this observatory location is the same location that Arnold Schwarzenegger arrives at from the future, finding Bill Paxton and some other thugs and stealing one of their clothes.
Trivia: The wound T-800 makes to Connor's face will become John's scar shown in T1 in Kyle's flashback.
