Movie actors sweating it out on location, take after take, tend to think that the fellow behind the camera is some kind of clown. Exactly so, in the case of Quick Change, a comedy being filmed in the streets of New York City this summer. The actors, including Geena Davis, Randy Quaid and Jason Robards, are going through their paces for a very funny chap, though he's scarcely recognizable behind all that makeup. The film's star and co-director: Bill Murray. No fooling.
