With Mel Brooks' big new musical version of "Young Frankenstein" having just opened on Broadway, the American Cinematheque's Aero Theatre is presenting the classic 1974 film comedy Saturday. Shot in glorious black-and-white, "Young Frankenstein" is Brooks' homage to the 1930s Universal horror films and stars Teri Garr, Gene Wilder and Marty Feldman (above, left to right), with Peter Boyle as the Monster. It plays on a double bill with Brooks' "High Anxiety." (americancinematheque.com). . . .
