Trivia: The movie being about the start of a major worldwide war (with a heavy use of technology too), an interesting coincidence can be seen in the first truck chase sequence. Just as John and the Terminator speed under the bridge that the T-1000 crashes into, a height warning on the bridge can be read which says "CAUTION 9-11". The truck smashes right into it. (00:36:15)
Trivia: When the T-800 is walking through the mall, he has got a box of Roses that is concealing a Gun. This is in reference to Guns N' Roses, who recorded the movie theme song "You Could Be Mine". Arnold also appeared in the music video, referencing lead singer, Axl Rose, as a "waste of ammo". (00:30:05)
Trivia: The character of Sarah was originally to have a knife scar on her upper lip to make her look harder and more feral than she did in the first film. However, since this would have meant a detailed makeup job every day, the concept was dropped after the first day or two of shooting. In some of the desert scenes, you can still see the scar if you look closely.
Trivia: Originally Michael Biehn was going to return...as the T-1000. The initial pitch was to turn the dynamic of the first film on its head completely by having the T-1000's default form look like Kyle Reese to contrast the T-800 being a good guy, with a longer sub-plot where Sarah had to deal with her savior and lover now being Skynet's weapon. The studio execs, however, vetoed this idea as too offputting to audiences, thus leading to Cameron going with the then unknown Robert Patrick as the T-1000.
