Dr. Carl Stoner (Strother Martin) experiments with snake venom which he injects into his intern (Dirk Benedict ) which slowly turns into a snake. Dr. Stoner is fascinated by the Garden of Eden story but never really ties it into the script. Lots of snakes. Some good snake trivia. Plot and characters are not that entertaining.

Guide: No swearing. Implied sex. Blurred nudity.

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.)

The film deals a mad doctor(Strother Martin),his former helper has disappeared and he asks to University professor(Richard B. Shull)a student. A young man called David (Richard Benedict)looking for employment is hired by the scientific.The doctor works a secrets experiments on snakes.Meanwhile David falls in love with his daughter(Heather Menzies).Then the ¨mad doctor¨ injects him a serum into becoming a King Cobra snake causing a horrible transformation.

The motion picture packs horror,romance,shocks and is quite entertained. In the film appear known actors from the 70s and 80s as Dick Benedict(¨Galactica Battlestar,A Team¨),Strother Martin(Peckimpah's usual player:¨Wild bunch¨),Heather Menzies(Robert Urich wife and little girl actress in ¨Sound of music¨)and Reb Brown(a beefcake who played many hunk men vehicles). John Chambers provides a deliriously imaginative make-up ,he won an Academy Award by the classic ¨Planet of Apes¨and made the sequels among others films(Phantom of the paradise ans Island of Dr. Moreau).Executive producers are Richard D. Zanuck and David Brown ,short time after they produced the successful ¨Jaws¨to Steven Spielberg. The motion picture is well directed by Bernard L. Kowalski who worked with Roger Corman.Slick film aimed at youthful audiences and terror lovers.
