Emmy® and Tony Award®–winning actor Sean Hayes of Good Night, Oscar stars as Elliott in The Unknown. A gripping new play about a writer on the edge.

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 and directed by Tony Award nominee Leigh Silverman that explores the fine line between fascination and obsession.
