What are some interesting mystery or scifi movies from 60s or 70s?

Rollerball
Planet of the Apes

I recently forced myself to watch zardoz.

That was a hell of a ride. I probably should have been high or something watching it but it was interesting.

Apparently the town that was that this movie was filmed in had a massive explosion of new births 9 months after this film was filmed, apparently everybody and their brother were all getting high and humping like bunnies throughout the entire filming and it makes me wonder how many bastard children of Sean Connery are currently living in Ireland

For sci-fi "2001: a space Odyssey" from 1968 would be an obvious pick

Some of these border on drive-in schlock or worse, but that's exactly what I look for in sci-fi movies of that era:

• A Boy and his Dog
• The Omega Man
• The Last Man on Earth
• The Terminal Man
• Futureworld
• Dark Star
• Laserblast
• Starcrash
• The Alien Factor
• This is Not a Test
• Mission Stardust
• Countdown (1967)
• Starship Invasions
• Silent Running
• Fantastic Planet
• Fantastic Voyage
• The Visitor / Stridulum
• Children of the Damned
• most Planet(s) of the Apes

So many good films mentioned here.

A nice little Gerry Anderson (Thunderbirds, Space 1999, etc.) flick is Doppelgänger (Journey to the Far Side of the Sun).

No one has mentioned Star Wars (1977) (later renamed Star Wars: Episode IV: A New Hope) probably because it seems too obvious. It changed SF, cinema and the media landscape forever.

Invasion of the Body Snatchers (1978)
