Desperate to cure his writer’s block, Elliott retreats to a remote cabin—only to discover he may not be alone. As the boundaries between his work and his life collapse, Elliott begins to question everything he knows. Is he writing a thriller? Living one? Both?
The Unknown is a provocative thriller by award-winning playwright David Cale that explores the fine line between fascination and obsession.

FEATURED REVIEWS FOR The Unknown
‘The Unknown’ Review: Sean Hayes Turns One Man Into a Mystery
7 / 10
The director Leigh Silverman treats the set (designed by Studio Bent) like a noir soundstage, filling it with hard-edge shadows (Cha See designed the lights) and banks of fog-like smoke. The primary quality, though, is sound. “The Unknown” is hypnotic, which is another way of saying that its pleasures are very quiet ones. I felt like I was listening to radio drama on a rainy night, or as if someone were reading me a familiar story, but I’d forgotten the ending. Waller-Bridge’s dreamy music sounds as though it’s coming from another room, and it’s only when Cale deploys certain haptic details — Hayes describes the spare keys to Elliott’s apartment, stuck with a magnet to his fridge — that the evening takes on momentary weight.
Sean Hayes’s Theme and Variations: The Unknown
8 / 10
The Unknown could use more of that menace. Throughout the production, and especially once Elliott’s circumstances start to get weird, director Leigh Silverman hits the audience with sudden, silent horror-film punctuation marks. The lights (by Cha See) will drop out and isolate Hayes in a beam of dread as he arrives at some further unsteadying discovery about his stalker. But those swerves into ominousness don’t linger, and Silverman and Hayes don’t keep us submerged for long.
