With Ridley Scott’s Alien: Covenant currently in post-production right now, star Michael Fassbender has revealed that he’s actually playing two roles in the film.

Speaking to The Irish Times, Fassbender, who played android David in Scott’s Prometheus, explained, “I am allowed to say I am playing two robots – Walter and David. I think what’s great about it is that Ridley has gone back to the original DNA of Alien, the horror element of that. But it also has the scope and scale of Prometheus. Ridley has cut it already. He is a machine. He is an incredible human being and he was in such good form. He is such an imaginative and mischievous figure.”

Fassbender is joined in Alien: Covenant by Katherine Waterston, Danny McBride, Billy Crudup, Demian Bichir, Jussie Smolett, Amy Seimetz, Carmen Ejogo, Callie Hernandez, and the returning Noomi Rapace as Elizabeth Shaw.

The official word on the film reads:

Set as the second chapter in a prequel trilogy that began with Prometheus, Alien: Covenant connects directly to Ridley Scott’s 1979 seminal work of science fiction. It begins with the colony ship Covenant, bound for a remote planet on the far side of the galaxy. There, the crew discovers what they think is an uncharted paradise, but is actually a dark, dangerous world – whose sole inhabitant is the “synthetic” David, survivor of the doomed Prometheus expedition.

At present, Alien: Covenant is set for an August 4th, 2017 release.
