So here’s the lowdown: Terminator Genisys was meant to start up a brand new trilogy of Terminator films that would have been more greatly interconnected that the first one. Producer David Ellison wanted to have his own cinematic universe ala Marvel studios, that’s why Genisys tried to create a clean slate for the franchise. That’s also supposedly why Matt Smith’s villain character was only in it for, like, 5 minutes, he was meant to be the trilogy’s ongoing Big Bad.
However, due to Terminator: Genisys’ lackluster box officer: only $89.7 million domestic, $350.4 million international, not even breaking even according to analysts, plans for the remaining Terminator sequels have been shelved.
Some sources claim this is due to Ellison’s lacking experience in creative direction for the franchise. However, others cite his involvement in the 4th and 5th Mission: Impossible films, saying there are other factors that may be in play.
Either way, plans for the Terminator franchise are on hold indefinitely.
