Prepare for a huge new update on "Terminator 5," now retitled "Terminator Genisys" (what a "Genisys" is- that's something we'll have to wait a little bit longer to find out). Enstars has published a massive new update on the fifth film in the "Terminator" franchise, detailing all the spoilers we know so far.

First and foremost, we know that Arnold Schwarzenegger is returning to the film after bowing out of "Terminator Salvation," the fourth film in the series (technically, he appeared at the end, but as footage of his younger self superimposed onto a similar-looking bodybuilder's torso, which was extremely strange and not technically a new Schwarzenegger appearance).

We also know that his character, the T-800, will have a convenient excuse for why an immortal robot has aged several decades in between the "Terminator" films- apparently, the skin that surrounds a Terminator robot can age, even if the 'bot underneath never does. Does that mean that eventually, we'll be surrounded by geriatric killer robots from the future?

According to a previous piece in Enstars, Schwarzenegger himself described the expanded use of time travel in "Terminator Genisys." Time travel is a hallmark of the "Terminator" films, but the fifth will go above and beyond in its take on the subject:

"Terminator deals a lot with time travel, so there will be a younger T-800 and then what that model does later on when it gets reprogrammed, and who gets a hold of him," said Schwarzenegger. "So it will be all kinds of interesting twists in the movie, but I feel so good."

Director Alan Taylor recently compared his take on "Terminator" to Christopher Nolan's Batman series, which is always a positive thing to hear. Here's what he told Slashfilm:

"Sure, that too, but Tim Burton's first Batman is just glorious and by the time it got around to nipples on costumes and all that stuff it sort of lost its way. And for [Christopher] Nolan to come in an say 'I respect this material so much I'm going to take it up to *here,* that's a great inspiration.' I think any version, whoever is directing Terminator, would be very respectful and serve the first two and probably feel a bit more freedom by the end."
