I'm not sure what you mean by 'no one seems to know', if it's low box office movies, I've got a few. The Michael Douglas reference reminded my of a couple.
Thinking of Michael Douglas:
- Wonder Boys - Decent movie about an English professor with life problems
- Falling Down - Might be too famous, but a lot of people I talk to haven't seen it and it's great
....
US Cinema:
- Nightcrawlers - Just saw this. Awesome film. Jake Gyllenhaal absolutely crushes it. Belongs on depressing list too I'd think. More Disturbing than anything though
- October Sky - Coming of age about a poor, coal miner's kid who grows up to be a rocket scientist
- Garden State - I don't know why more people haven't watched this. Classic indy film
- Rescue Dawn - Christian Bale. Vietnam POW movie. Underrated under seen.
Sci Fi selections:
- Moon - If you're a fan of sci fi and you haven't seen this, there's something wrong with you
- Man From Earth - If you're a fan of sci fi and you haven't seen this, there's something wrong with you
- A Scanner Darkly - Dystopian Phillip K Dick number. This movie was a flop, but was actually awesome. It was shot digitally, then animated over the top. Great cast. Keanu Reeves, Winona Ryder, Robert Downey Jr., Woody Harrelson
- The Island - Here's a weird option which doesn't quite fit the title because: Michael Bay. $126m budget. Stars Scarlett Johansson and Ewan McGregor. Huge Ad campaign. And yet, very few people have seen it! Grossed like $36m; $12.5m opening weekend. Quality Sci fi imo.
- Primer - great time travel sci fi movie made for only $7,000!!
Special Addition. I think most on the Yard have heard of it, so perhaps doesn't qualify, but it's a must watch.
Idiocracy. Taken at face value, a horribly bad movie. But actually a piece of brilliant satire. It's meant to be bad on purpose. One of the most relevant movies by which to view modern society. Theme song of the Cesspool.
Cult classics in Australia (but not here in the US):
- Chopper - brutal "true" story about about a real life bicycle gangster
- The Castle - Light hearted comedy. THE Australian cult classic. You get to see what a great Character actor Eric Bana is in his first role. Not for everyone.
- Romper Stomper - Russell Crowe before he became Russell Crowe. A low budget movie about Aussie Skinheads
- The Proposition - An Australian western directed by musician Nick Cave. Really underrated
While we're talking Foreign Films, because most Americans haven't seen them, I've got a ton. Some really popular, some not so:
- The Orphanage - Spanish Horror/Thriller. Really freakin' creepy. Foreign horror movies are better imo (The Ring etc)
- Old Boy - Crazy Korean thriller. Also brilliant.
- La Haine - French day in the life of 3 ghetto kids in a time of unrest. Probably won too many awards for this list
- Un prophète - French gangster in prison. Also probably won too many awards for this list
- Death at a Funeral - British dark comedy. Absolutely hilarious. Peter Dinklage
- Withnail and I - British cult classic. Weird. Loved it though. Some of you might need subtitles to understand the English being spoke.
- This is England - Coming of age story with skinheads
- Dead Man's Shoe's - for a straight up no frills revenge flick. Paddy Considine.
etc, etc, etc
Foreign films remade, which are often well known here, but the originals were way better.
- Let The Right One In - Ok, it was remade in the US to a bit of popularity. But the original was, way better. Brilliant Scandi flick
- Die Welle - German movie where teacher does play acting nazi experiment with classroom
- El Secrete de Sus Ojos - Argentina. Better than the crappy remake
- The Ring - Japanese. Holy crap. that's how you do a freaky movie
- Abre los ojos - Better than the crappy Tom Cruise remake Vanilla Sky
etc, etc, etc
I could go ham on listing foreign films all night. I think they make better movies these days. Real story. Real characters/actors. Not as much about 'selling' as they are about 'creating'.
