The Devil Bat. 1940.
After being cheated out of a fortune, a mad doctor develops a lotion and gives it to a rich family hoping to entice a genetic bat to attack and kill them.
Given the time era and budget the tacky special effects with the bat flying and close ups may have worked with it's screeching may seem laughable now in this little B movie. Bela Lugosi plays the Doctor who develops the lotion as aftershave lotion and spreads it to family members who got rich from his work. Dave O'Brien and Donald Kerr play the reporter and photographer who seem interested in the story as their editor wants pictures, always a entertaining film to come back to.
