'Terminator: Dark Fate' first official trailer: Arnold Schwarzenegger and Linda Hamilton return

Nearly four decades later, Arnold Schwarzenegger and Linda Hamilton are back in the trailer for "Terminator: Dark Fate."

The highly anticipated film hails from "Deadpool" director Tim Miller and producer James Cameron and is the sequel to the franchise's previous films, "The Terminator" and "T2: Judgment Day."

"Dark Fate" features "Hamilton's" Sarah Connor back in action as she defends the world against evil robots who want to destroy it. It also introduces Mackenzie Davis as a new hybrid terminator/human, Grace.

“Never seen one that looks like you,” Connor says to Grace “Almost human.”

“I am human," Grace responds.

"Terminator: Dark Fate" hits theaters on November 1.
