THE MAN WHO WAS THURSDAY is inspired by the existentialist novel of the same name by G.K. Chesterton (1908). The novel is considered a metaphysical thriller, and our film could be considered the same, though it also can be thought of in more classical cinematic terms a psychological and supernatural thriller.

Grace, a young widow haunted by the recent suicide of her husband Joseph, is falsely accused of being a witch by her Landlord after she rejects his advances.
