Via Plutonica, a Life magazine  slideshow on Aleister Crowley and his influence on pop culture.

I had not known that Sidney Blackmer played his character, Roman Castevet,  in the occult thriller Rosemary’s Baby, partly on impressions of Crowley.

When the movie came out, I was too young to appreciate the depth of its scariness, let alone know who Crowley was. I should watch it again.
