Gymkata
Gymkata is a 1985 martial arts film starring Olympic gymnast Kurt Thomas as Jonathan Cabot, an Olympic gymnast who combines his gymnastic ability with martial arts to enter a deadly competition in a fictional country, Parmistan. The film is based on the 1957 novel The Terrible Game by Dan Tyler Moore, adapted for the screen by Charles Robert Carner (of Blind Fury fame), and shot in Yugoslavia. Gymkata earned a Razzie Award nomination for Thomas as Worst New Star.
It has developed a minor cult following as an unintentional comedy for its dubious premise, poor production quality and strange setting. Maxim lists the film as the 17th "Worst Movie of All Time".
