Dunston Checks In

What happens when a pet orangutan runs wild in a five-star hotel? Not as much as you'd think, but it isn't for lack of trying. Faye Dunaway camps it up as a Leona Helmsley type. Rupert Everett sports fake buck teeth as an inept jewel thief. Even Sam (Dunston) gives a tricked-up performance, augmented with vocal effects and human costumes. Everyone tries too hard, except Paul ''Pee-wee Herman'' Reubens, who doesn't try hard enough as an animal catcher. Too dull for kids, too dopey for adults, Dunston Checks In should be rented only if your video store is out of Bedtime for Bonzo. C-
