The Character "Cameron" is a tribute to James Cameron, who came up with the idea of Terminator and directed the first two movies.
FBI agent Ellison is named after Harlan Ellison, the science fiction author whose work inspired the Terminator movies.
Summer Glau got the role of Cameron based partly on the strength of her fight scenes in Serenity (2005). Josh Friedman wrote the character with Glau in mind.
During Derek Reese's flashback scene in the future, we learn that Andy Goode was so ashamed of his involvement in creating Skynet that he began using the alias William "Billy" Wisher. William Wisher Jr. is a long-time collaborator of James Cameron, the creator/director of the Terminator films. Wisher also co-wrote the screenplay for Terminator 2: Judgment Day (1991).
German broadcaster Pro7 renamed the show to "Terminator: S.C.C." because the name was deemed too long and to avoid confusion with German celebrity/singer Sarah Connor.
The word "terminator" was not spoken by any character until the finale of season two, "Born to Run," where Sarah Connor referred to Catherine Weaver as such.
