A part of the film score for the upcoming addition to the 'Terminator' franchise has allegedly leaked through a fan site.

The 13-second long audio clip which is supposedly taken from the upcoming 'Terminator: Genisys' film has since spread all over the Internet.

A quote about the audio clip reads, "This music was apparently made for a terminator factory scene and the building of T-800s in mind."

However, a disclaimer was posted by the website saying that the audio clip has not been confirmed as authentic.

Meanwhile, the movie's lead actor Arnold Schwarzenegger confirmed that the team successfully wrapped up the shoot for the forthcoming movie through an Instagram post.

"Hasta la vista, baby. I want to thank the cast and crew of @TerminatorGenisys for a fantastic shoot. It was challenging, it was fun, and it was rewarding. From our director to the producers, from the camera team to catering, from visual effects to hair and makeup - we couldn't have done it without you. I can't wait to see our finished project and I know we'll remind the fans why they fell in love with the Terminator. On July 1, 2015, I'll be back," reads Schwarzenegger's photo caption.

Paramount Pictures confirmed that 'Terminator: Genisys' will be the start of a new trilogy, and that its additions will be released in 2017 and 2018.

In the said movie, Alan Taylor takes on the directorial duties, while Emilia Clarke, Jai Courtney, Jason Clarke and Dayo Okeniyi act alongside Schwarzenegger.

Unfortunately, fans are still uncertain about the plot of the upcoming 'Terminator' movie. Some reports say that the movie will be a reboot, while some say it would involve a time travel plot.

In an interview, Schwarzenegger confirmed that the movie would involve some sort of time travel.

"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," says Schwarzenegger.

'Terminator: Genisys' hits theaters on June 26, 2015 in United Kingdom, and July 1, 2015 in the United States.
