It was a movie we watched in religion class since it has a ton of Christilogical references, kinda like the matrix does, except more obvious.
Its about a man being sent to jail for something petty (going against athority) much as Jesus did. He finds the rules and regulations of the jail "bosses" to be rediculous and unnecessary, much as jesus found the laws of man (created by religious athorities).
Its an old flick, like from the 60's, but its in great quality when on DVD.
And the car washing scene, man, great scene. When the teacher went out to get some scantron sheets scanned, we just kept skipping the chapter back to the carwash scene.
