Williams stars alongside Jeff Bridges in this drama directed by Terry Gilliam. Bridges’s character, shock jock Jack Lucas, inadvertently pushes a psychotic radio caller over the edge and suffers a breakdown himself after finding out the caller has committed a massacre. Several years later, while working as a clerk at a video store and heavily depressed, he is rescued from an attack by homeless man Parry, played by Williams. He becomes involved with Parry and finds he is connected to the tragedy that caused his own downfall. Jack must rescue him in an urban re-imagining of the legend of the Holy Grail and the Fisher King.
Parry is a man with a previous life that was so damaged that he had to create another personality … Some people respond to traumatic or tragic events by withdrawal; some even create other personalities. Parry is a creation -- somewhat Don Quixote, somewhat Groucho Marx -- but he’s a creation designed to avoid a past event.
