Robert Crumb, the multi-talented underground comic book artist, is profiled in   this unique, in-depth documentary portrait. Emerging from a dysfunctional        family, it's a wonder that Crumb managed to channel his peculiar take on the     world into a relatively socially acceptable form. Part of the great            fascination of this film is the revelation that his brothers, both also quite  gifted, were not as lucky.                                                     Terry Zwigoff---USA---1995---119 mins.
