"Terminator: Genisys" really invigorated the robot franchise and took it to new depths when they presented a completely unexpected villain in its latest movie.

When the villain was defeated and the lead characters managed to find their happy ending, director Alan Taylor want audiences not to feel too complacent, because something else is brewing.

During the movie's post-credits scene, which lasted for a mere 10 seconds, audiences witnessed a ball of glowing red light, with Genisys, represented by a blue light in the shape of a child, standing next to it. This only means that the efforts of Sarah Connor, Kyle Reese, and the Guardian to obliterate the robot uprising were all in vain, and they still have something to contend with.

"It was always there as a kind of gateway - to further developments... It's precisely a kind of, 'it's not over yet' moment," Taylor told Cinema Blend. "On the one hand, it's one of the things that points to there being further chapters. On the other hand, this is a kind of franchise where I don't think anybody really believes that you're going to end up neatly or happily. So, when our heroes drives off into the sunset and we think, well that went well. There's still going to be a nagging feeling that wait, it's not that easy."

During the final scene in "Terminator: Genisys," Sarah Connor and Kyle Reese finally share a happy kiss as "Pops" looks on, and they mull a peaceful future together  - one that does not involve getting Reese killed off, which was his supposed future. But Taylor confirmed their story's not over yet.

"There is, in fact, a final resolution to that paradox that I know Skydance has in mind, and it will be wonderful if they get a chance to bring that out in further, in later chapters. But the post-credits scene is pointing to later chapters, and at least saying, 'It's not that simple,'" he said.

In fact, there might be a chance that John Connor will be brought back from the dead. The actor who played him, Jason Clarke said that he will not be surprised to see his character return for the next few "Terminator" films, despite being destroyed by Arnold Schwarzenegger's Guardian in a sacrifice move in "Terminator: Genisys."

"I think he's still a fascinating character to explore. And I know they're up to something," he teased.
