this movie chronicle the life and time of william castle . he make a series of low budget horror film in the 1950s 1960s that he sell with gimmick . in 13 ghost you need viewer to see the ghost ( they be in color and the film be in b and w ) . the tingler have theatre seat equip with a buzzer that jolt the audience when a monster escape into a movie theatre . marabre issue a life insurance policy to all member in case they be frighten to death . the movie themselves be pretty bad but the gimmick have people rush to see them . in this doc there be interview with director inspire by castle and actor in his movie and his daughter . it also get into his home life and the kind of man he be ( by all account he be a great guy ) . the documentary be affectionate and very funny and absolutely rivet . it very short ( under 90 minute ) and there never a dull moment . a must see for castle fan and horror movie fan . my one complaint there be very few sequence show from his picture . that aside this be just great .
