In "Portrait of Jason," filmmaker Shirley Clarke trains her camera on Jason Holliday, a down-and-out hustler in 60s Los Angeles, who has led a particularly rough life -- he's gay and black, and thus especially well placed to speak about prejudices of various kinds. Jason is a flamboyant, street-wise hustler, and the entire film places him at its center, swilling liquor, talking incessantly, and even at times launching into impromptu performances. This alcohol-soaked portrait reels and spins with its subject, veering wildly from one hilarious anecdote to another, even as beneath the bluster and the chatter, Jason's inner sadness begins to leak inexorably through. This is a deeply moving and humanistic film, a powerful portrait of the fate of the outsider in American society, and the unique challenges faced by one such outsider.
