Most know Mae West only from groundbreaking comedies like I'm No Angel. But Simon Louvish, using clips and the star's personal archive, re-creates her rich vaudeville years singing and shimmying, followed by her hot-button plays Sex (for which she was jailed), The Drag (exploring homosexuality), and The Pleasure Man (more homosexuality, plus castration) in Mae West: It Ain't No Sin. Just as fascinating are details of West's battles with Hollywood censors. (A note for Belle of the Nineties curiously suggests deleting the line ''It pays to be good but it don't pay much.'') While old age was unkind, in 1978's Sextette she did get to say the F-word on screen.
