Plan 9 from Outer Space

Two or three aliens in silk pajamas conspire to resurrect several slow-moving zombies from a cardboard graveyard in order to conquer the Earth. Spaceships that look suspiciously like paper plates, blaze across the sky. Pitiful, inadvertently hilarious fright that's worth a look if you're desperate to kill time, since it's in the running for the "dumbest movie ever made" award. Lugosi's actual screen time is under two minutes, since he had the good sense to die before the film was complete. Enjoy the taller and younger replacement (the chiropractor of Wood's wife) they found for Lugosi, who remains hooded to protect his identity.
