The Devil Bat

Bela Lugosi plays a small-town chemist who breeds a giant bat and trains it to attack anyone wearing a cologne he invented. He uses it to take revenge on the family he believes cheated him, handing out the cologne as a free sample and then sending the bat after each victim. A reporter and his photographer, played by the comic team of Dave O'Brien and Donald Kerr, arrive to investigate the strange deaths. It was the first horror film from Producers Releasing Corporation, one of the poverty-row studios, and Lugosi gives it more gravity than the budget deserves. The film was a surprise hit and PRC made a fortune on it. It entered the public domain and has circulated in countless cut and restored versions ever since.
