I came across this brief article in a back issue of Fantastic Adventures magazine (August, 1940).
The source isn't the most credible. (I don't think Fantastic Adventures peer-reviewed its articles.) But the story made me curious enough to do a google search to try to figure out where this drug 'anhalonidin' came from. A lot of the search results discuss it in connection with the cactus lophophora, from which comes the drug peyote. That kinda makes sense, I guess. Though I'm not sure if lophophora grows all the way down in Colombia.
Humphrey Bogart regarded this as his biggest dog of a film. He plays a mad scientist who went to the electric chair, died, was revived with "synthetic blood," then had to subsist by draining the blood of others.
And here's the weirdest thing: almost every scene in this trailer is an outtake, not seen in the actual film! I wonder if viewers of the era felt ripped off.
