a few must-watch hidden gems:
1. The Thief and the Cobbler (1992, dir. Richard Williams)
An unfinished masterpiece of animation. 31 years in the making from the animation director of Who Framed Roger Rabbit (1988).
2. Tetsuo: The Iron Man (1989, dir. Shinya Tsukomoto)
Early mind-bending Japanese cyberpunk/body horror. According to Wikipedia, it's "considered to be one of the greatest Japanese films of all time." I'd have to agree.
3. My Breakfast With Blassie (1983 dir. Linda Lautrec, Johnny Legend, Mark Shepard)
Advanced (meta)comedy from the master of cringe-core/performance art Andy Kaufman at the peak of his powers. Will blow the minds of those on its wavelength.
