Deathsport

Deathsport is a 1978 science fiction B-film produced by Roger Corman and directed by Allan Arkush and Nicholas Niciphor. The film stars David Carradine and Playboy Playmate Claudia Jennings. It would be one of Jennings' last films before her death. Plot "A thousand years from tomorrow" after the Neutron Wars, the world is divided into a barbaric collection of city states surrounded by wastelands where only mutant cannibals and independent warriors, known as Range Guides, can live. Led by Lord Zirpola, the city state of Helix is planning war on another city state, Tritan, for their fuel supply. Hoping to prove the superiority of their newest weapons, the Death Machines (laser-equipped dirt bikes), they create a new pastime - Deathsport. The death penalty has been replaced by Deathsport, where criminals battle each other to the death in return for gaining their freedom. Lord Zirpola has managed to capture legendary Range Guide Kaz Oshay (Carradine) and he wants to add a female Range Guide for an upcoming Deathsport event. A female Range Guide, Deneer (Jennings), is captured while leading a group of Tritans across the desert. A child, Tara, is taken by the mutant group during the attack to capture Deneer. In a Helix jail, Kaz Oshay bonds with Deneer and vows to escape with her and find the group's child. After enduring torture and facing his mother's killer, Ankar Moor, Oshay and Deneer are forced onto the Deathsport motocross field, which is mined with explosives. They easily defeat the other riders and escape from Helix with two other prisoners, Dr. Karl and his son Marcus. During the escape, though, the doctor is killed.
