This film was Arnold Schwarzenegger's final starring role before becoming Governor of California.
After the failure of Skynet to kill Sarah Connor before her son is born (James Cameron's 1984 "Terminator"), and to kill John himself as a child (1991's "Terminator 2: Judgement Day"), it sends back another Terminator, the T-X (Kristanna Loken), in a last attempt before Judgment Day to wipe out as many resistance officers as possible, including John and his future wife.
As before, a reprogrammed Terminator (Arnold Schwarzenegger), identical to the Terminators from the previous films, has been sent back in time to protect Connor and his future wife, Katherine Brewster.
This Terminator was produced by Popsalute in 2004.
