This feature-length film (2000) of Margaret Cho’s potent one-woman show recalls the early stand-up films of Richard Pryor 20 years ago. There’s the same confessional fervor and pain-ridden comedy deriving from a restaging of traumas having to do with identity crises and substance abuse. As a 31-year-old Korean-American, former alcoholic, star of a discontinued sitcom, and self-described “fag hag,” Cho has plenty of issues of her own. But there’s a similar kind of hilariously cathartic autocritique as she examines her efforts to lose weight and become “less Asian” when her sitcom was in jeopardy, and her priceless impersonations of her mother offer a pungent concentrate of her complex responses to racism. It’s hard to think of many more galvanizing definitions of what it means to be an American than Cho’s volcanic self-assessments. 90 min.
