There are some films that truly defy any kind of explanation. Some are just so bizarre, so over-the-top that explaining the plot out loud draws more than a few looks from bystanders. Here's some of the most bizarre / outlandish films out there...

5. 2012 (2009)

Yes, that one with Roland Emmerich. If you've never watched it, take time out and enjoy yourself. John Cusack as a limo driver, that's weird. The world is being destroyed by... well, everything, we guess. Not only that, you've got tidal waves coming over the Himalayas – which is actually impossible. No, really. There's not nearly enough water in the world for that to actually happen. Then there's a scene where a plane flies into a subway and comes out again. Because the crust of the earth is breaking up. We shit you not.

4. BRAZIL (1985)

Terry Gilliam – the director of Brazil – is known for making weird-ass films. He made Fear And Loathing In Las Vegas and a bunch of other crazy films. Brazil tops all of these. How? Well, the entire film is just bonkers. Firstly, the title of the film has absolutely nothing to do with Brazil. At all. It's not even set in Brazil. The film is actually based on George Orwell's 1984. Yes, that super-depressing book you read in school about Big Brother. Not only that, Robert DeNiro turns up for, like, five minutes and then isn't referred to again. Yeah, really.

3. KATE & LEOPOLD (2001)

It's a film about a time-travelling sailor who falls in love with Meg Ryan. The time-travelling sailor is Hugh Jackman with the most put-on English accent you've ever heard. And how does the film end? SHE TIME-WARPS BACK TO THE NINETEENTH CENTURY WITH HIM. Yeah. We're done. G'luck now.

2. LOCK, STOCK & TWO SMOKING BARRELS (1998)

The problem with Lock, Stock & Two Smoking Barrels isn't the whole idea or plot behind it. It's more about the casting. Specifically Sting. You have to wonder what was going through director Guy Ritchie's head when he sat down and thought, "Let's get New Wave singer and Police frontman Gordon Sumner AKA Sting to play a Cockney landlord." We're not saying musicians can't become actors, but Sting as a gangster? Moreover, a successful gangster with a bar and having Bricktop as one of your barmen? Nope. Too far. This is a man who - and we're not joking either - fought off a mugger by quoting Shakespeare at him. Yes, really. This is the man who can convincingly play a London Cockney gangster.

1. COWBOYS & ALIENS (2011)

The title alone is just plain daft. Cowboys... and aliens. Say it again, out loud. Now, let's move it along. Daniel Craig as a cowboy? That's James Bond, English actor and all-round genteel man as a vagrant gunslinger. Directed by whom? Jon Favreau. Iron Man's Jon Favreau. The rich boyfriend Monica had who was really into MMA in that episode of Friends. That guy. And then Olivia Wilde shows up. And is also an alien. Yeah, we're confused too.
