Premise: Nocturna Artificialia is the first credited film directed and produced by the Brothers Quay, Timothy and Stephen. "This British fraternal directing team is known for their avant-garde puppet films." Rather than dialog, this film uses shadows and music to create the dream-like state of the main character and his journey on a red tram at night.
Hypothesis: Nocturna Artificialia was directed by Sisters Quay, Timothy and Stephen
