The film is best known for a famous promotional gimmick used in the film's original theatrical release called "Emergo": William Castle placed an elaborate pulley system in some theaters showing the film which allowed a plastic skeleton to be flown over the audience at the appropriate time. In August and September 2010, the Film Forum in New York City had a revival of the film (along with several other Castle pictures) that included the original gimmicks.
Check out that ghost. I know I would have crapped my pants seeing that move up the aisle towards me.
6/10 For classic old school nostalgia.
