Well the OP himself clarified his request and a cult film is one with a cult in it. A fact 99% of the posts in this thread have decided to ignore. Which is fine. Talking about films is always good.What's a cult film?
Pffft, elitist alternative sub culture snowflaking or what!
Betchya gone with the wind and the Wizard of Oz are two of the biggest films of all times with a past audience, a current audience and no doubt a future audience... Cult?
I tend to think of cult films being those that inspire an obsessive following and don't fit neatly into a mainstream genre rather than necessarily having to be unpopular, but that might just be me.
Can we count Dune as a cult movie?
If so this
Withnail and I.
Reading through the thread many of the films listed aren't even close to cult films. Metropolis (cinema classic), Mad Max 2 (franchise movie, and not even the first in a franchise at that), The Thing (again I favourite of mine).
Monty Python and the Holy Grail, Jaws, Ghostbusters, The Terminator - all great films, but none of them are cult films. I love Fight Club, but it's not a cult film it's like saying Ther Matrix is a cult film, or calling GOT or Soparanos a 'cult' TV shows.
The Big Lebowski is a cult film, but Alien isn't a cult film, both are all-time faves of mine. Fear and Loathing in Las Vegas is a cult film, Repo Man is a cult film, Brazil is a cult film, Time Bandits is a cult film, Napoleon Dynamite is also. Boondock Saints? YES!
It's hard to believe they were able to make Robocop on a budget of $13m. As a kid it was one of the first movies I saw that was rated 18 (it was either that or Predator 2) and loved it for it's gory violence and as I got older I appreciated more for the themes it presented and the satirical in movie adverts (a Paul Verhoeven trope as he used them again in Starship Troopers). These days is watching it is like being stabbed by the needle of nostalgia.the greatest Sci-Fi films ever, many of the messages are ringing true even now... Hard to believe this film was made 30 years ago.
