I saw it, in the theater. 
It is (or was the last time I noticed) on Netflix’s Watch Instantly service, along with some other fine documentaries. That’s really what I replied to say - being proud of having seen such a nerd movie is just gravy.
The Godfather of Green Bay - a comedian, desperate for his big break, follows the talent scout for “The Tonight Show” up to Green Bay, and gets mixed up with the mob on the way.
Mr Vampire - The first and best of a series of Hong Kong vampire movies. No garlic and stakes: they fight vampires with rice and martial arts.
7 Faces of Dr Lao - Fantasy comedy western with Tony Randall playing seven different parts. Bonus: Joel of MST3K said this is his alltime favorite movie.
The Specials - Comedy about a third-rate band of super-heroes on their day off.
I’d like to offer a hearty second recommendation for this, thus making it ineligible for the thread.
Great comedy.
Stars Jamie Kennedy, Rob Lowe (right before his stock went up with West Wing), Thomas Hayden Church, Judy Greer, John Doe and Jenna Fischer from the Office has one line (her future/now ex husband made the movie)
Janji Joni (English title Joni’s Promise) - Indonesian film about a film messenger trying to get the second reel of a movie to a theater in time to get the girl. Everything that can go wrong, will go wrong, and hilariously. Funny, cute, good music.
“No one else has seen?” Well, judging from the previous posts, that’s a pretty tall order in this crowd, but I’ll try anyway:
The Villain–Comedy western starring Kirk Douglas–funnier than Rustler’s Rhapsody, IMHO.
Massacre at Central High–The “revenge movie” by which all others are (or should be) judged.
I liked that one. It was like Jesus Camp, except about a font.
The 5000 Fingers of Dr. T. Mad piano teacher with 500 captive students.
Let’s Kill Uncle – A young heir to a fortune learns his uncle wants to kill him for his fortune, and decides to kill him instead. Really quite good.
Le Trou (1960, French, black-and-white) Has to have grand themes, like classism, but is mostly a really cool prison-escape movie.
I went to see this one in the theater! Kirk Douglas as the bad guy, Arnold Schwarzenegger as the good guy (with his “seven shot six shooter”), Ann-Margret as the girl, and Paul Lynde as the Indian chief. It was basically a live-action Road Runner cartoon. 
Is that the one that’s like a live-action Looney Tunes cartoon? Funny film. (As is Support Your Local Sheriff with Jim Garner, similar vintage.)
And filling_pages, I saw The Fabulous Stains 20 years ago, so though it may have been re-released recently, it’s not been completely sequestered since it was made.
Another recommendation: Cranford, which was actually a BBC miniseries. Killer cast headed by Judi Dench and Imelda Staunton. Small-town life in England immediately before the railroad arrived, based on a novel by Elizabeth Gaskell. Each one-hour episode has a smaller focus, but there’s an overall narrative arc as well.
Ok, maybe not no one, but [REC], the Argentinian movie that Quarantine was based on. Don’t let the Blair Witch Project style shooting put you off. It’s way easier to watch, and scary as hell.
And, it’s available, in parts, on youtube. Watch it in full-screen mode. I can’t recommend it enough. One of the best horror movies I’ve seen.
Highway 61
A Canadian barber travels to the US with a former Roadie. Hijinks ensue, including angering somebody who may or may not be the Devil. The excellent Canadian actor, Don McKellar, stars.
Harrison Ford at the beginning of his career, sultry Lesley-Ann Down, solid Christopher Plummer and charasmatic, though underused, Richard Masur, and the greatest backdrop in movie history (WW II) combined with impactful acting, heroic drama and a powerful and clever script climaxed with an ending which will cause even the most hardy person to choke on tears. Man, how does this movie languish in obscurity?
Ha! I’ve seen this one. The thread title clearly states “no one else has seen.” Are you having trouble with reading or comprehension? You fail.
…that is always my recommendation for these kinds of discussions, and the one I opened this thread to nominate.
Umm. Besides the movie listed in the OP, I’ll nominate May, a 2002 “horror” film about a socially awkward woman who only had a doll as a friend as a child, and tries to make real friends with tragic results as an adult.
Hey – play nicely. As the OP, I was trying to suggest that people talk about films that most people haven’t seen or heard of, and that seems to be what most of the suggestions are about.
Oddly, this was the answer to a clue in today’s NY Times crossword puzzle.
I saw this one as a kid. Scared the crap out of me.
My pick - Hellzapoppin Olsen and Johnson movie based on the Broadway show, which I saw on TV as a kid and finally found on video. Even better than I remembered.
Yeah, I know. That was a bit of a “he-he.” I think it would be impossible to expect that absolutely “no one” has seen the above listed movies.
