Woman in the Dunes (1964) directed by Hiroshi Teshigahara

This movie was wild. It has such a unique story to begin with, and it's wrapped up in a haunting score and sound design, phenomenal cinematography that feels sensual and vulnerable, and an incredible set design and location that amplify the atmosphere.
It tells the tale of this teacher (Niki) who goes to a beach (that resembles a desert more than anything) to collect some insects, he stays for the night in a woman's "house" and is then tricked into becoming the villagers' slave essentially. All of his attempts at escaping generate some incredibly tense and at times shocking scenes. I was very impressed to see that during his first try at climbing out of this hole he's in, he ignites a huge sand avalanche that knocks him back down. Looking at it all happen you would think that the film had a bigger budget than it really does, but no that's just the kind of confidence it walks around with, and it's present and strong throughout the entirety of its runtime. Just a few minutes later, we see Niki getting lifted up by the villagers with a rope, only for them to sadistically and mockingly drop him back down clearly impacting the floor hard, this all being in one continuous long take. So yeah, this movie was pretty wild.
The film also puts in contrast the life that our main characters share with the life of the average person and his 9 to 5 city job, which showcases the overwhelming similarities between the two seemingly different lifestyles, only this time, Niki is shoveling sand from 9 to 5 instead of teaching. However, our main character eventually discovers an actual purpose after being forced into this environment for so long. Not only has he grown a little attached to the woman he's with, and not only is she having his baby, but more importantly, he discovers a technique to draw water from a damp sand by capillary action. With the latter, he breaks the monotonous cycle he's been living in all of his life, and feels he has now accomplished the first meaningful thing he's ever done. That is why he chooses to stay in the end. He will make substantial accomplishments and have more of an impact in this deserted village than he ever will in Tokyo.
We also have the woman in this film (who we only know as "the woman") who is the emotional string of it all. After finally having a companion in Niki, there's a shining light in this dark tunnel of loneliness she's been trapped in for what seems like now an eternity. In reality, I think she'd even do double the work she's already been doing just to keep him as someone to talk to and accompany her throughout this life she's living. And because Niki is so passionate about leaving this place, and he's from the city, she's constantly comparing herself and the life she can give him to what he's known and had available in the past. She wants him to care for her just as much as he would normally care for someone back home, and not just because of the circumstances they're in. She wants to be enough for him, and she wants him to be satisfied with what they have and what they can be.
Meanwhile he's building a grappling hook (which I'm still confused on how he managed to even do that) behind her back and manipulates her emotionally in order to sneak out smoothly. After another gripping failed attempt though, we can see how his acts truly affect her and her self-esteem. Then there's of course that heartbreaking rape attempt, which reminded me a lot of the cow scene from
Apocalypse Now in terms of feels and form. Even though the woman would do anything to please this man at this point, she absolutely refuses to stoop that low and fights desperately for he life. And of course she would because otherwise letting him have his way would validate all of her insecurities of being lesser than.
