Warrior of the Lost World, also known as Mad Rider, is a post-apocalyptic science fiction film written and directed by David Worth starring Robert Ginty, Persis Khambatta, and Donald Pleasence. It was created and first released in Italy under the title Il Giustiziere della terra perduta ("The executioner of the lost earth") in 1983 during the wide popularity of the Mad Max films and many subsequently created post-apocalyptic films of the 1980s.
The warrior is traveling through a post-apocalyptic world on his technically advanced motorcycle and his loyal computer Einstein. Being pure in spirit, he manages to pass through the wall of illusion and meets the resistance movement The Elders, fighting the tyranny of the evil despot Prossor. The resistance asks him to free professor McWayne, their leader, who has been sentenced to death by Prossor. The beautiful Nastasia and the warrior infiltrate the city, guarded by the Omega militia, where the professor is imprisoned. Written by Mattias Thuresson
