It's hard to be certain of anything in A24's delightfully bizarre and surreal The Lighthouse. Except for one indisputable fact: Damn, that is some capital-A Acting.

Willem Dafoe and Robert Pattison deliver two of their most iconic performances as two hardened 1890s lighthouse keepers trapped all alone together on a rock in the middle of a violent ocean. Every exchange between them is mesmerizing, from hilarious drunken bonding to fear-of-god striking ancient sea curses.

In this exclusive clip provided to Mashable, watch what is by far the best exchange between them, when a light criticism of Dafoe's cooking leads to one of the most intense monologues of the Oscar-nominated actor's career.

Hark! A pro tip! Do not insult William's lobster recipe, folks.
