I was reading Roger Ebert's review of the 1994 Jean Claude Van Damme movie Timecop and thought it was strange that Roger referred jokingly to a hypothetical Terminator sequel by its actual eventual title, "Terminator 3: Rise of the Machines." Terminator 3 wasn't released until 2003, almost a decade later.
Ebert gets my additional praise for understanding even back then that the Terminator premise had already been fully realized in Terminator 2 (which he praised). It took me a few more movies to get to the same conclusion...
Last paragraph of the review:
And yet, the more I thought about it, the more I realized that the movie's logic is sound. It's not so much that the premise of the original "Terminator" has been ripped off, as that Hollywood went traveling into the past and inalterably ripped the fabric of time, and that's why we got "Timecop" with Van Damme instead of "Terminator 3: Rise Of The Machines" with Schwarzenegger. You see what can happen.
