Rollerball 15

In the not-too-distant future, a group of all-powerful corporations have taken over the day-to-day governance of the entire planet. War is now a thing of the past; the human race can only work out its violent tendencies by watching 'rollerball', an internationally televised blood-sport. Jonathan E. (James Caan) is the star player for a team owned by the Energy Corporation – but his employers, worried that his growing fame makes him dangerous, have plans to force him into retirement. A bleak and uncompromising vision of a nightmarish future under capitalism, Rollerball is one of the finest dystopian films of the 1970s.
