The Tingler
The Tingler is a 1959 horror shlock monster send-up produced by exploitation gimmick auteur William Castle, whose stable of low-rent films always featured an added "bonus" for audience members: a free Rasputin beard, "life insurance" for anyone that should happen to die of fright during the viewing of his Psycho kock-off Homicidal (1961), and, in the case of The Tingler, select theater seats wired with joy buzzers or electrodes or some shit, to shock the asses of the American monster movie-going public. (Needless to say, he would have been sued, arrested, possibly deported, or even executed for trying such shenanigans in modern times, particularly if his little stunt resulted in some unsuspecting movie patron having a massive coronary. At the very least, he would have faced a civil suit due to "emotional trauma".
