Dunston Checks In (1996)

Robert is the beleaguered manager of a luxury hotel owned by Mrs. Dubrow. She tells him that an undercover reviewer is coming and to look sharp. If he does well, he might get a promotion and some time off to take his sons, Brian and Kyle, on vacation. But then a villainous jewel-thief named Lord Rutledge checks in with his specially trained orangutan, Dunston. And when Dunston gets loose and tries to escape a life of crime with Brian and Kyle's help, things go just a little lunatic.
