Which actor played the T-800 in Terminator: Dark Fate?

Arnold Schwarzenegger played the T-800 in Terminator: Dark Fate.

Schwarzenegger returns as a version of the machine character first introduced in The Terminator. In Dark Fate, the T-800 uses the human name Carl and has spent years living quietly after completing its mission.

The film presents this incarnation differently from the protector T-800 in Terminator 2: Judgment Day. It also introduces Gabriel Luna as the Rev-9, a newer and more flexible Terminator sent after Dani Ramos. Schwarzenegger's return is one reason Dark Fate is treated as a continuation of the first two films, although its story is not identical to the earlier continuity.
