Beetlejuice

Beetlejuice is a film about a malevolent ghost named, yes, Beetlejuice. One can summon him from the underworld or dismiss him by speaking his name three times. Of course, once Beetlejuice has been called up, he doesn't want to leave...ever. When Barbara (Geena Davis) attempts to get rid of him, he uses his supernatural powers to shut her up.

 First he conjures up a zipper to seal Barbara's lips, and then, when that proves ineffective, he raises the stakes by bolting a metal plate over her mouth.
