The latest promo for Tim Miller's upcoming Terminator: Dark Fate features the delivery of an iconic line -- and it comes from a surprising source.

The extended television spot is mostly an abbreviated version of the film's first trailer. It shows Dani Ramos and her protector, Grace, come under attack from the Rev-9 Terminator, only for Sarah Connor to show up and open fire on the killer robot.

At the end of the promo, however, we see Sarah continue her attack on the Terminator, as she drops a grenade over a bridge. "I'll be back," she then tells the two awestruck women in her care.

The "I'll be back" line was first spoken by Arnold Schwarzenegger's titular character in The Terminator. He would later repeat the line in the film's sequel. Now that James Cameron has returned to the franchise as a producer, it's time for Sarah Connor to deliver the signature line.

Terminator: Dark Fate is said to take place after the events of Cameron's first two films. Not only is it a sequel to Terminator 2: Judgment Day, it's also meant to be a new beginning for the franchise as Hamilton and Schwarzenegger pass to baton to a younger cast.
