Spasms

Spasms is a 1983 Canadian horror film directed by William Fruet.

The screenplay by Fruet and Don Enright is based on the novel Death Bite by Michael Maryk and Brent Monahan. The production ran out of money before shooting was finished and the final scene had to be heavily padded with flashback sequences in an effort to lengthen the movie to a respectable runtime. The films special effects were designed by Dick Smith.According to interviews with director William Fruet and some other people involved in movie at the time when it was released, longer version of the ending fight between Oliver Reed and giant snake was planned and filmed, it included parts where he stabs the snake and snake swallowing his arm but due to the problems with effects the scene was not finished and had to be cut. Scene where sailor who is bitten by snake gets his arm swallowed by it was also cut, and there was also a nightmare sequence in which some victims of the snake show up covered with gory wounds. Director said that he shot some additional violent scenes for the Far East versions of the movie but none of these sequences were ever reported to be included in any version of the movie. ........
