The stars of next summer’s Terminator: Genisys cover this week’s Entertainment Weekly, and revealed to the magazine that the first of Paramount’s three planned Terminator films will relaunch the beloved sci-fi franchise. Entertainment Weekly’s exclusive interview reveals that the upcoming filmwill rewrite the origin stories of several of the franchise’s most iconic characters, a move which is already worrying die-hard fans.

In the original Terminator, John Connor sends his friend Kyle Reese back in time to 1984 to protect his mother from a robot programmed to kill her so she’ll never give birth to mankind’s future savior. However, the Sarah Connor of Terminator: Genisys will have a much different first encounter with the infamous terminator portrayed by Arnold Schwarzenegger. In the film, Sarah Connor – portrayed by Game of Thrones‘ Emilia Clarke – was reportedly orphaned at a young age by a terminator and was then raised by Schwarzenegger’s terminator, whom she calls “Pops.” This turns Sarah into a highly-trained yet antisocial recluse warrior at a young age, which will mean Clarke’s portrayal will be incredibly different from Linda Hamilton’s initial appearance as Sarah Connor.

“Since she was 9 years old, she has been told everything that was supposed to happen,” explained producer David Ellison. “But Sarah fundamentally rejects that destiny. She says, ‘That’s not what I want to do.’ It’s her decision that drives the story in a very different direction.”

This major plot change has already angered fans of the original film, who have been quick to mock the idea and voice their outrage online. However, former Doctor Who star Matt Smith, who plays one of John Connor’s friends in the upcoming film, believes that Genisys pays proper tribute to the original Terminator.

“It’s like going on tour again if you’re Pink Floyd—the audience always wants to hear some of the old songs,” said Smith. “There are enough nods to the past that people will feel satisfied.”

The film will hit theaters on Jul. 1, 2015
