I watched a movie in 1990's. It's about the people and creatures live together in the world . There is an agreement between them.Almost all people don't know that they are living with creatures because they see creatures as a human. Only few people see the creatures real face with only a special mirror (or sthg). In one scene a man accidendaly see one of a creature's real ugly face when the creature apply make-up and man says" It's like pig wearing perfume on it" I can only remember these. I apreciate anyone help me to find out the name of this movie.
