Uncredited actor in "The Lighthouse"

I'm trying to learn the identity of an uncredited actor from "The Lighthouse". He plays the man whose memory haunts Ephraim (Pattinson). Ephraim "sees" him in visions from behind, and imagines him in place of Thomas (Dafoe) when the two are fighting. I went to IMDB, but only Pattinson, Dafoe, and Valeriia Karaman (Mermaid) are listed. Any idea who he is?
