15. Barton Fink (1992)
The film: The Coens' dark and insular writer's block movie, written while they themselves were struggling to pen Miller's Crossing. It's downbeat, it's depressing, and it features a raging John Goodman who may or may not be the devil.
Join the cult: Being near-inexplicable but stuffed with ripe symbolism, Barton Fink has several fan sites devoted to discussing what the hell it all means.
14. Evil Dead 2 (1987)
The film: Sam Raimi's mucky horror-come-remake of his first film, Evil Dead. The formula's the same - a big-chinned hero in the woods with baying demons and buckets of blood - only this time the film's more professional and kicks more ass.
Join the cult: Leading man Bruce Campbell has become such a B-movie institution that he's played himself in a recent genre monster mash, and Evil Dead fans - or Deadites - are still going strong on the net.
13. Akira (1988)
The film: The blistering neo-noir anime which single-handedly popularised Japanese animation in the West and featured enough looming cityscapes, post-nuclear telepaths and insanely cool motorbike chases to power at least three cult smashes, let alone one.
Join the cult: Check out the super-passionate fan site Akira 2019, which includes the precise specifications of Testuo's bike. Or actually try building one of the things yourself, like this chap here.
12. This Is Spinal Tap (1984)
The film: Rob Reiner's cringe-inducing, super-convincing faux rock-doc featuring the hairy talents of Brit rockers Spinal Tap. The film was played so straight it left audiences baffled during its initial run, but gathered pace on video and eventually led to spin-offs and real live tours.
Join the cult: Until the Tap tour again, your best best is the awesome spinaltapfan.com, which includes an amazing A-Zed encyclopedia of the band.
11. The Shawshank Redemption (1994)
The film: Mega-inspirational prison film with Tim Robbins the Christ-like innocent Andy Defresne convicted of killing his wife and serving his time in prison with integrity and dignity. The film is a grower: it missed out to Forrest Gump at the '94 Oscars, but built up critical momentum and a huge fanbase on home release.
Join the cult: As the film's reputation grows so do its fanatics. The scene-by-scene analysis at this fan site shows how devoted the movie's audience is.
10. Repo Man (1984)
The film: Alex Cox's punky upstart angst-flick, starring a nowhere-to-go Emilio Estevez as a drifting kid whose life falls into some kind of twisted meaning once he begins work as a repo man.
Join the cult: Check out the location tour and - best of all - the guide to being a real life repo man at frenzied fansite repomanfilm.com.
9. Twin Peaks: Fire Walk With Me (1992)
The film: The feature length spin-off from David Lynch's bright burning but short lived television mystery series, which like the show itself is full of quirky characters and cosy Americana contrasted with dark mysteries and strange abstractions.
Join the cult: To experience the ultimate cup of joe and slice of cherry pie, visit the Twin Peaks Fest, which features celebrity guests, screenings and location tours.
8. Freaks (1932)
The film: Tod Browning's extraordinary and way, way ahead of its time drama about circus freaks, with a cast consisting mainly of real carnival attractions. Hugely controversial (it was banned for decades in Britain) it resurfaces on the underground film circuit in the Sixties and gained a counter-culture following.
Join the cult: Chant "One of us! One of us!" at every opportunity - the chant taken from the film's most famous and frequently referenced scene.
7. Showgirls (1995)
The film: A sleazy cinderella's tale of a small town girl heading to Vegas to make her name, only to become tangled in a web of sex and lies and awful acting. The worst 'so bad it's good' film of all time, which also of course means it's the best.
Join the cult: The VIP DVD - released after studio MGM realised people were holding ironic Showgirls parties - comes with drinking games, shot glasses, and a naked poster of Elizabeth Berkley with suction cup plasters to put on her nipples.
6. A Clockwork Orange (1971)
The film: Stanley Kubrick's cold and stylish adaptation of Anthony Burgess' already controversial novel has enough vigour and cool outfits to have become a cult sensation regardless, but nearly three decades of self-imposed absence of British cinemas made it a unobtainable gem.
Join the cult: Before Kubrick's death and the film's re-release, catching a secret screening would have been top priority. Now we'd suggest holding a Clockwork Orange-themed party. Like, um, Christina Aguilera.
