Ronald Tavel's THE LIFE OF JUANITA CASTRO is one of Andy Warhol's triumphs as a filmmaker. A playwright (Tavel himself) taunts a number of actors into improvising a truly ridiculous but subtlely meaningful meditation on Fidel Castro and his family, at a time when the revolution was bringing back disquieting stories of executions and imprisonments and, particularly, virulent hatred and torture of homosexuals in Castro's Marxist paradise. Hilarious as JUANITA is,it remains a history lesson wherein fascism itself is on display and the audience is encouraged to laugh---but with some discomfort.
