Was watching The Hunger Games with the girlfriend last night.
Couldn't help but think how similar it was to Logan's Run, Battle Royale and Death Race 2000.
Started telling my GF about dystopian future film trends from the 70s, 80s and 90s and how each focused on different future concerns.

Like how 70s films focused on society, 80s focused on lack of resources and cyberpunk (low life, high tech), while 90s films were usually about the internet.

Just wondered if you guys could recommend more dystopian films?
Never watched Soylent Green for example, but heard it's good.
