Arnold Schwarzenegger and Linda Hamilton are back, together. The two are reuniting on-screen for the first time in 27 years — since 1991’s Terminator 2: Judgment Day — for the film currently known simply as Terminator 6. Schwarzenegger is very different: His T-800 android, an assassin whose subsequent models have been protectors, was, in T2, a tight piece of work with short, spiky hair.
