Rates are low decor is rococco art deco and the clientele is... convivial. As a Cleveland sanitation company owner reasons this New York all-male bathhouse is ideal for hiding from his murderous brother-in-law. But what this new arrival and his fellow patrons get is an exercise in manic mayhem from director Richard Lester bringing Terrence McNally's hit Broadway farce to spicy screen life. Adding more spice are five cast members of the stage original: Jack Weston Jerry Stiller F. Murray Abraham Paul B. Price and especially Rita Moreno as clueless Googie Gomez the role for which she captured a Tony-« Award. Kaye Ballard and Treat Williams add to the tasty guest list. Check into the Ritz. You've got roomfuls of laughter to check out.
