You haven’t seen a movie musical until you’ve experienced it Cinerama-style. As proof, they’re showing three classic movie musicals in one day, giving you six blissful hours of admission to that fantastic parallel universe where people break into song with almost no provocation. If you’d like a break from having your eyes and ears lovingly fucked to the brink of ecstasy, you should skip South Pacific for a long walk and an early dinner—West Side Story’s sweeping pathos and My Fair Lady’s pastel-colored charm should make for more than enough delight for a single day. (Cinerama, 2100 Fourth Ave, 448-6680, WSS at noon, SP at 4 pm, MFL at 8 pm, $12 each)
