The script handles an absurd premise with a degree of straight-faced amusement. Feathery voiced Strother Martin acts his head off as the mad scientist. He has the entire show in the palm of his hands, talking to his snakes, even feeding them alcohol and at one point reading them Walt Whitman. The use of real snakes is effective, especially when it comes to the various set-pieces bumping off victims. The script holds no real surprise as to what is happening to Dirk Benedict, even though the film takes three-quarters of its running time to unveil this. The snake man makeups are subtly effective, although the finally transformed snake is disappointing and lets down on the careful build-up down.
The film has an interesting cast who all moved onto fame in various late 1970s tv shows Dirk Benedict starred in Battlestar Galactica (1978-9) and The A-Team (1983-7); Heather Menzies became Jessica in the tv version of Logans Run (1977-8); Tim OConnor was Dr Huer in Buck Rogers in the 25th Century (1979-81) and the following tv series; Reb Brown became the title star of two miserably failed tv pilots, Captain America (1979) and Captain America II (1979); and Richard B. Shull went onto Holmes and Yoyo (1976). Of course, executive producers Richard Zanuck and David Brown would also move onto Jaws (1975) a couple of years later and then the likes of Cocoon (1985), Driving Miss Daisy (1989) and Deep Impact (1998), among others.
