5. Battlefield Earth

Poor John Travolta; fresh from career rejuvenation with Pulp Fiction, he walked straight into this absolute flop. Wildly considered to be one of the worst films ever made, this adaptation of L. Ron Hubbard’s novel of the same name features an odd but entertaining performance from Travolta as Terl, the security chief of an alien race who have conquered Earth.  Jonathan Ross was particularly scathing of the film, saying "Everything about Battlefield Earth sucks. Everything. The over-the-top music, the unbelievable sets, the terrible dialogue, the hammy acting, the lousy special effects, the beginning, the middle and especially the end."

4. Evil Dead II

Unlike most of the films on this list, Evil Dead II isn’t a bad film, it’s quite the opposite. Certified 98% fresh on Rotten Tomatoes, Sam Raimi’s parody-horror sequel is considered by many to be better than the original, but there’s no denying it’s downright insane. Bruce Campbell’s unhinged performance as the terminally unlucky Ash Williams has gone down in history as a horror classic, and it’s spawned sequels which were decent films in their own right, but none will ever be as good as Evil Dead II, quite possibly the king of cult horror.

3. Anonymous Rex

Imagine a world where dinosaurs had never been extinct. Instead, they faked their own extinction, and were living peacefully alongside humans in disguise as private investigators and such. Well- you don’t have to imagine, because this is the premise of Anonymous Rex, which is actually based on a novel called 'Casual Rex'. Starring lesser known Baldwin brother Daniel and Sam Trammell (of True Blood fame) there’s really not a lot more than can be said for this film. Except that it’s no Jurassic Park.

2. Snakes on a Plane

One of the more famous titles on this list, Snakes on a Plane became an internet sensation long before its release due to its title, plot, and the casting of Samuel L. Jackson in the lead role, further proof that the man can do whatever he wants. It’s a case of a film doing exactly what it says on the tin: there are snakes, on a plane, and everything else is really a bonus.

1. The Room

Explaining The Room to someone who hasn’t seen it is a little like explaining complicated mathematics to a Labrador: you can try all you like, but they will always look at you ultimately bemused by the words coming out of your mouth. Directed, written and produced by its lead actor Tommy Wiseau, this so-called ‘romantic drama’ focuses (in the loosest sense of the word) on a love triangle between a banker, his fiancée, and his best friend. Featuring a cast of unknowns, an indecipherable plot full of inconsistencies and non-sequiturs, the film has somehow become an international sensation, spawning a video game, Rocky Horror-style interactive midnight showings, and with a whole host of celebrity fans behind it. Seeing really is believing.
