Eyes Wide Shut.

Full Metal Jacket!

When I first saw Blade Runner soon after it came out. What really got me was the sci-fi film noir that was juxtaposed with the hauntingly beautiful soundtrack by Vangelis. And then of course many years later came the Director's Cut! Mind blown again. Vangelis refused to release the soundtrack for many, many years,as he did not want to be heard outside the film.

The original Star Wars.That got me thinking about forces being neutral, depending on how you use them.
I, and several members of my family, were born psychic, so we knew that "God" wasn't the one doing the stuff we could do (water witching, ESP, seeing the future, etc.) since it came naturally, from birth, and had nothing to do with "religion."

Brazil. Certain aspects of that movie still haunt me to this day.

Watched the original Phantasm entirely too young. Think about that movie every time I visit a cemetery to this day. Nothing recently has had that effect. :-/

(No mention of David Lynch films? This is no cinema discussion! I'm outta here.)

Mulholland Drive is probably his more famous film about this topic. But more so The Lost Highway. Both films present how, for some of us, our minds cope after a traumatic experience.

But those are just for real mind zingers - when you go WTF after watching them.

Ex Machina was the film that stuck in my head days after seeing it. The Turing Test isn't about whether an AI could pass for human. But whether it could while you know it's AI.

The shining...

Donnie Darko.

the old version of Handmaids Tale, with Duvall. creepy.

the Bothersome man....stayed in my head a long while.

The grudge

Fried green tomatoes at the whistle-stop cafe

A Clockwork Orange always makes me think new thoughts.

A good "old" classic. Dark City. Great Sci-Fi noir

When I was younger ie in my teens me and my mates took acid and got stoned then watched the exorcist. freaked the living fuck out of all of us.

Psycho. Watched it at the Rialto theater with my mom. Mistake.

The last Star Wars.

Night of the Living Dead. I ain't been right since.

Apocalypse Now. Woodstock. Bangladesh. Tommy. Heavy Metal. Mad Dogs and English Gentlemen, The sensualist, Jesus Christ Superstar, Godspell, The Pearl, Altered States... It was not the movies... it was the level of intoxication of the experimental substances.
