Exploitation movies of the '30s and '40s have seldom received much respect. Even during the era when drug-scare movies such as Reefer Madness and Narcotic attracted large audiences on the roadshow circuit, exploitation movies were sliced and diced by their owners. The editing scissors of clever producers and roadshowmen struck like dull meat cleavers, snipping out a segment here, pasting on a new segment there. New movies rose from the remnants of old movies. Movies with 70-minute-long running times, suddenly were chopped to 45 minutes so they could fit on double bills.
