Scanner Darkly from 2006 by Richard Linklater. It stars Iron Man, John Wick and Carnage... I mean, Robert Downey Jr, Keanu Reeves and Woody Harrelson. It's a rotoscoped "5 minutes into the future" sci-fi paranoia thriller that's horrinfyingly topical 15 years later with its themes of drug addiction, surveillance state, the war on drugs and corporate power. You could release it today and not even be able to tell when it's from. And it's based on a story originally from the fucking 70s! It's also got an Alex Jones cameo. Yes, you read that right.
End of Evangelion might be an odd choice to put on here since it requires seeing an entire TV show to be able to grasp what's going on even barely (and that's as good as you'll be able to anyway). I don't even like the movie, it's a 5/10 at best, but its cinematic merits are undeniable. The technical aspects of it are top notch, there's some incredible visuals and setpieces, the voice acting is legit some of the greatest ever recoreded and to this day I can think of no other film quite like it. It's also interesting in the sense that I can think of no other film that's so much less than the sum of its parts. I like to view it as an unintentional comedy, because you can legit put the lines in some scenes in random order and have it make exactly as much sense.
I also know it's a very new release and super mainstream by being by James Wan, but I do genuinely think that Malignant is a gem for all lovers of cinema. It's got genuinely great camerawork and effects, it's got tons of references and homages to horror films of the past, it plays with and on conventions of horror movies, and it seems like Wan had total creative control over the project. It doesn't feel compromised in any way, and its vision feels completely untouched. I can't say what moves it into the category of "really, really, really odd" without spoiling the whole thing, so you'll just have to take my word for it. See it in theaters if you can, you won't regret it.
