James Cameron is writing Terminator 7, but there’s one big challenge that’s getting in the way. Released in 2019, Terminator: Dark Fate was an attempt at relaunching the long-running sci-fi/action franchise via a legacy sequel, with Arnold Schwarzenegger and Linda Hamilton returning alongside a cast of young actors. The attempt largely failed unfortunately, as the film grossed just $261 million on a reported budget of $185-196 million. After Dark Fate met its somewhat dark box office fate, the Terminator franchise went into seeming deep-freeze, with Schwarzenegger recently proclaiming that he is done with the series for good.
