Apparently our hero, George Weiss, found himself dabbling in the harder stuff by the time the mid '60s came about. Title character, Olga, is a drug-runner and brothel madam with a penchant for violent interrogation. There are snitches and double-crosses galore, all perfect excuses for Olga to flaunt her techniques. The film is also noted for having very little sync sound as it was clearly made well into the period of Weiss' career as a producer where frugality was beyond essential. Of course, if it made any money it had other installments, namely White Slaves of Chinatown and Olga's Dance-Hall Girls.
Cult release specialist company "Something Weird Films" offers a triple disc set of the Olga series. Apparently they are tame by today's raincoat-wearing viewer standards but I'm sure they divvied out the kicks in their day. Thanks again, George Weiss!
