Ssssilbido de muerte

A college student becomes lab assistant to a scientist who is working on a serum that can transform humans into snakes.

This film is far from perfect. It could use a few more horror or science fiction elements, perhaps. Where it excels is with the use of real snakes and the knowledge that the professor has. I am not a herpetologist, and would not claim to be any sort of snake expert. But when the professor is explaining different things about snakes, it sounds very real, like he really knows what he's doing. So, well done on the script.

The premise is a bit silly, but not overly so. This seems like the sort of thing that might be in a 1950s movie rather than a 1970s film from Universal. Director Bernard Kowalski (1929-2007), perhaps not surprisingly, is a veteran of such Roger Corman-produced films as "Night of the Blood Beast" and "Attack of the Giant Leeches". (Kowalski was director on both, but you can imagine that Corman had his fingers in the pie.)
