The third evening in PFA and San Francisco Cinematheque's ongoing series of artists' 8mm films and videotapes, selected from the Museum of Modern Art, New York, retrospective. The three films on tonight's program confront viewers with women interacting with girls and other women in the most intimate settings, using the immediacy of 8mm. The results are candid and complex psychosexual portraits of themselves as women, and of their imaginative inner lives. Jacalyn White's In Mother's Way is a riveting portrayal of the filmmaker's mother as she shares her sexual fantasies, experiences, and sense of herself as an aging, late middle-aged woman. Peggy Ahwesh's Martina's Playhouse disarmingly records the taboo sexual tensions-both stated and unstated-between two women and between a mother and her daughter. Gail Vachon's Mary Smith offers vignettes of the filmmaker acting out a variety of familiar social roles.-Steve Anker
