The Spook Show was an offspring of the growing interest in the supernatural and the contacting of the dead through mediums. The mediums were largely phonies that used the grief of people over lost loved ones as a way to fill their pockets. The mediums all developed tricks that could be performed in the absolute darkness they needed to contact the dead...and hide the wires, fishing poles and accomplices needed to produce the "spirits".
Spook Shows continued into the 1950s and1960s were they began to merge into "Monster Shows" where monster movies were screened, a supernatural magic act was performed and actors in monster costumes would run loose in the audience, usually in pitch darkness. The popularity of these shows waned as the 1970s began until they all but vanished...
Until a recent trend in new revival Spook Shows began. In Atlanta fans can see the Silver Scream Spook Show held at plaza Theatre where host Morte runs a cross between a Horror Movie Host show and a traditional Spook Show. Dr Scream runs a travelling Spook Show Revival Show throughout the Midwest. A little digging online my lead you to a Spook Show in your own town. As for your humble host here, the malevolent Monterfink,I live in a town with three MAJOR colleges and a community college....think I'm gonna start looking for a theatre to rent and some public domain B-Movie goodness and have me a Spook Show of my own.
