Instead of wars, there's Rollerball... The mid-'70s were ripe with sci-fi movies depicting a dystopian and/or post-apocalyptic future, from Soylent Green and The Omega Man to Logan's Run and the Planet of the Apes series. Enter 1975's Rollerball, starring James Caan, the story of a futuristic, corporate-controlled society in which the elite enjoy watching regional teams battle it out to the death in a controlled arena. Sound familiar? Just for the record, make sure you watch the 1975 version of the film and avoid the cringeworthy 2002 remake at all costs.
