PAUL REUBENS, creator of America's favorite case of arrested adolescence, Pee-wee Herman, promises not united but two upcoming films featuring his adenoidal avatar. hum on the first film has been about its "adult" nature, and Reubens says, "I'm not suppos to call it the adult Pee-wee movie, the dark Pee-wee movie, because it's not scary, it's not dark, and it's not really adult." He does, however, add rather forebodingly, "It's not a kids' movie."
