Hilarious comedy from the masters of the absurd, this film purports to explain the meaning of existence through a series of sketches. We explore topics such as birth, sex education, middle age, and death. Occasional profundity shows its head (such as the scene where a couple go to a restaurant to order a conversation, not a meal), but occasionally the humor is the more obvious puerile kind. Like most sketch movies, the quality varies. Best of all is the opening short, “The Crimson Assurance,” a terrific Brazil-like film by Terry Gilliam. It opens with a ship of slaves being whipped to work harder, then morphs that into the same old men working at desks as accountants. From there, the men overthrow the suits and put a pirate flag and set forth on the “accountancy” (emphasis on the final syllable). Hilarious and yet quite deep on many levels.
