Principal photography on the Terminator movie franchise reboot – heavily rumored to be titled Terminator: Genesis – began more than a week ago, yet over the past few days we’ve gotten some additional casting news for the film. Arnold Schwarzenegger is confirmed to be playing an aged version of the T-800; unofficially, the movie’s storyline is said to involve Arnold’s old cyborg protecting Sarah Connor (now played by Game of Thrones‘ Emilia Clarke) at different points and events in history – including, moments that were depicted in previous Terminator installments.

Actor and body-builder, Aaron Williamson may well be playing the young version of the T-800,; if the rumored storyline is accurate, then he might be helping to recreate scenes featured in past Terminator movies in Genesis, among other things.

Casting-wise, we also know for certain that Jason Clarke (Dawn of the Planet of the Apes) is playing an older John Connor from the post-Judgement Day future setting, while Jai Courtney (Divergent) is the latest actor recruited to play John’s father, Kyle Reese. Last, but not least, Dayo Okeniyi (The Hunger Games) will play the grown-up son of the man responsible for designing the technology that, in the previous Terminator films, led to the A.I. Skynet.

Skydance Productions has now officially confirmed that ex-Doctor Who star Matt Smith – who, obviously, is no stranger to the time-traveling/sci-fi sub-genre – will be playing a role in the upcoming Terminator reboot. In addition, Deadline is reporting that Smith will have a “major role” in the movie, which shall grow into something even more substantial in the second and third installment in the new planned Terminator trilogy (which, rumor has it, will be shot back-to-back).

Smith, you may recall, was also rumored to join the cast for Star Wars: Episode VII over the past year, and will next show up in Ryan Gosling’s directorial feature debut, Lost River (previously known as How to Catch a Monster). He’s clearly been interested in pursuing a larger film-acting career since finishing his tenure as The Doctor, so it should be interesting to see how prominent Smith’s mysterious Terminator character becomes in future installments – assuming they happen, of course.

Indeed, seeing how director Alan Taylor (Thor: The Dark World) is the one calling the shots on Terminator: Genesis – drawing from a script written by screenwriter/producer Laeta Kalogridis (Avatar, Shutter Island) and writer/director Patrick Lussier (Dracula 2000, Drive Angry) – it’s difficult to gauge just how this film is shaping up, as far as its artistic quality goes. With a strong cast in place for this fifth Terminator installment and beyond, though, that’s at least one good sign for the future.

Terminator: Genesis opens in U.S. theaters on July 1st, 2015.
