One at random that I enjoyed that I don't think is well known is "God Bless America (2012)".

The title might be misleading, so I'll say that it is not a religious or patriotic film.

Dunno what you might expect with obscure or niche, but if you're fishing for random non algorithm suggestions on something you could watch, I'll give you this: Fantastic Planet (1973)

Two movies I don't think I've met anyone who's seen.

Young Einstein (1988)
Super fun, slightly accurate, biopic.

Spaced Invaders (1990)
Not good, but still funny alien invasion movie

I dunno about obscure but I owned Meet the Feebles on VHS.

I love telling people it's by the guy who did Lord of the Rings.

I also subjected my friends to A Boy and his Dog and The Wicker Man without telling them anything about them going in.

They loved both.

The Greasy Strangler had a very minor theatrical release and is a fantastically weird movie I love to recommend.

“Street Trash” was one of the movies ever made.. if you’re into terrible gross out b-movies it should be at the top of your list

I don't know if it's obscure, but Psycho Goreman is a fantastic movie and I can't recommend it enough. Anything by Steven Kostanski, really.

Also Termitator if you speak French and can manage to get a copy is hilarious.

Six-String Samurai, imagine if Elvis was literal King of Las Vegas, dies and leaves a power vacuum that send numerous baddies on a mission to become king, and Buddy Holly can not only play the axe, he can handle a katana blade even better. In hindsight this could just be a fallout movie with a few tweaks.

Honorable Mention: Wild Zero, very loud Japanese punk band Guitar Wolf takes on zombies with their instruments and maybe some magic?

Honorable Mention 2: Delivery, a pizza delivery driver is shit on constantly by everyone around him until he snaps and basically kills everyone who fucks with him.

Series 7

It wasn't popular and it took forever to get on DVD, while also being an hysterically dark take on reality TV. No idea why it didn't end up a cult hit.

Netherbeast Incorporated (2007)

No one I know has ever seen this movie. Dave Foley, Darrel Hammond, and uh... Steve from Blue's Clues... in a delightfully weird vampire office comedy.

Not counting the ones made by family members, Forbidden Zone.

The Tune (1992) by Bill Plympton is definitely an experience. Hausu (1977) is a weird fever dream. Dead In the Water (2006) was co-written & directed by a friend and is a decent indie zombie movie. It was fun seeing his parents cameo as zombies and then have Thanksgiving dinner with them.

Gundress (1999) is the most obscure anime movie I've seen and maybe also the most obscure movie overall -- of stuff that was actually professionally made and shown in theaters, anyway. I posted about it in one of the weekly anime threads a couple months ago with some screenshots and additional details.

Outside of anime, I've seen a number of cult films and non-English films that are probably obscure to English speaking audiences, but I have no idea how obscure they actually are. (The one above I know is obscure since it doesn't even have an English Wikipedia page -- unlike every other anime show and movie I've seen.)

Some examples are Wonderwall (1968) with music by George Harrison, eXistenZ (1999), Cemetery Man (1994), and I Served the King of England (2006). I know at least one other person on Lemmy has heard of Cemetery Man since it was brought up in a thread around Christmas, but they were surprised I'd seen it.

Primer (2004) and Dark Star (1974) also came to mind, but I don't think those are actually that obscure. They are interesting though.

Edit: rephrased for clarity

Edit2: typo in title fixed ("Kind" -> "King")

Freaks (1932)

Not the most obscure but i never would have watched it if not for my Goth friend in high school

An Argentinian Sci fi movie called Moebius. Broke my fucking teenage mind. The theme still is relevant and the msssage is more sound than ever.

Thanks to Lemmy, I recently watched umami's "Interface". Beautifully animated surreal adventure. Really enjoyed the weirdness, myself.

Who Killed Captain Alex - Uganda's first action movie

Begotten is probably the most inaccessible I've seen. Least known I used to do some 48-hour film festival we'd watch everyone's in a local theater at the end and most of those never get a general release so any of those are the least available or seen. Most indies I'll watch these days are horror or drama movies. One of my favorites is the man from Earth not exactly underground but definitely under most radars.

Paradise Now is almost like a non-comedic version of Four Lions. Both are worth a watch.

Not sure how obscure it is, but The Lure is a Polish musical about carnivorous mermaids who get jobs in a nightclub. I fucking love it.

Blood Quantum.

Went to school with the writer/director, so it's fun for me picking out all the landmarks I recognize. But it's also a commentary on the play on words of the title. And who doesn't love a gory zombie movie?

For me, probably Incubus, the 1966 Shatner flick filmed in Esperanto https://www.wikiwand.com/en/Incubus_(1966_film)

"A Letter to Dad" with an updated ending shot 10 years later. I would not recommend.

I've seen quite a few via mystery science theater

Tanpopo was one of the more... interesting experiences I've had lately.
