With the underwhelming performance and reviews of Terminator: Genisys, it should come as no surprise that Paramount Pictures has put any future sequels on hold, indefinitely.
Even though the studio pulled in $440 million worldwide on a budget of $155 million, marketing costs have to be put on top of that, and I'm sure Paramount really splashed out on marketing for the new Terminator movie in hopes it would win big at the box office. The Hollywood Reporter wrote that Terminator: Genisys is still losing money, even with the $440 million box office haul.
