In the creepy clip, Dafoe’s character, Thomas Wake, can be seen quizzing Pattinson’s, Ephraim Winslow, about his secrets, asking repeatedly: “Why’d ya spill your beans?”
Winslow, meanwhile, insists he’s not hiding anything – though the trailer’s mysterious atmosphere suggests otherwise.
The Lighthouse was a sensation at the Cannes Film Festival in May, earning rave reviews.
Pattinson, meanwhile, previously opened up about the harsh filming conditions he faced while shooting the film.
“That’s the closest I’ve come to punching a director,” he told Interview Magazine.
“However much I love [director] Robert [Eggers], there was a point where I did five takes walking across the beach, and after a while I was like, ‘What the f*** is going on? I feel like you’re just spraying a fire hose in my face.’
“And he was like, ‘I am spraying a fire hose in your face.’ It was like some kind of torture.”
The Lighthouse, directed by Robert Eggers (The Witch), is scheduled for release on 18 October, 2019.
