Produced for the "ultimate edition" of "Rollerball" from Capelight Pictures in Germany, 2020. The Blu-Ray of the original 1975 classic comes packed with this fascinating 85-minute documentary that charts the influence of "Rollerball" on contemporary scifi cinema, including "Mad Max", "The Warriors" and "Escape from New York", as well as the Italian variant that struck the big time with motion picture successes such as "The Bronx Warriors" franchise, "The New Barbarians" and the wonderfully trashy "Endgame".
