The Lighthouse 4K 2019

The 1890s, somewhere off the coast of New England. A young man, Ephraim Winslow, arrives on a remote island to work as the new assistant to the lighthouse keeper, a limping, bearded drinker named Thomas Wake. The latter treats his subordinate like a personal slave and forbids him to climb the lighthouse itself and operate the light. Ephraim cannot let go of his own past, so at first he refuses to drink, and soon all sorts of devilish things begin to happen on the rocky island.
