A quick last-minute Christmas competition for all you Advent Calendar openers - the chance to win this poster for The Girl with the Dragon Tattoo:

(Piano not included.) 

Yes, you can win this specific poster. Partly because it's Christmas and I'm feeling generous, but mostly because I went to London's @MouthTapedShut preview screening of David Fincher's very awesome film and accidentally picked up two posters on my way out.

If you would like to win this accidentally-acquired leftover super-amazing (probably) limited edition Dragon Tattoo poster, simply email adventcompetition@i-flicks.net with the name of the Dragon Tattoo star whose name has been jumbled up to make this phrase:

Helicopters Hmm Purr

Send your answers by 22:59 Monday 19th December (that's tonight). A winner will be picked at random.

Please include your postal address (UK only, ta) and your Twitter username, and who knows? If things turn out well, Santa might well dump the poster on your doorstep before Christmas Eve.

(Note: You cannot exchange the poster for a cash prize of £2.50, or whatever the Royal Mail delivery cost for a poster is.)

It's cold and dark outside, but you know what? Around the world right now there are 15 people having an orgasm. Such is the knowledge of Amelie, which was released in cinemas exactly 10 years ago and has just made it to Blu-ray for the first time ever. But you know what else Momentum have released as part of their new Contemporary Classics collection? Eternal Sunshine of the Spotless Mind - which, as everyone knows, was the best film of 2004.

The best thing about the release of Michel Gondry's heart-breaking, mind-bending movie (written by the super-amazing Charlie Kaufman)? we're giving away two free copies!

What better way to warm yourself up this Christmas than snuggling up with a high-def Kate Winslet and her ever-changing multi-coloured hair?

"This company makes a whole line of colors with equally snappy names. Red Menace, Yellow Fever... That'd be a job, coming up with those names." "I don't know... How many hair colors could there be?"

All you have to do to win a copy of Eternal Sunshine of the Spotless for Christmas...

You may think this is an ordinary Wednesday in August. You'd be wrong. It's actually 100 days until Harry Potter and the Deathly Hallows (Part 1) is released - and Emma Watson's counting. Or someone else definitely is, because the actress who plays Hermione Granger announced that to mark the countdown, 100 tickets to the Deathly Hallows World Premiere would be given away.

Where? Why, on Facebook of course! And how? Via a new Harry Potter app (of course). The app, Join the Battle, is another step in the massive worldwide Potter frenzy as fans gear up for the concluding episodes of JK Rowling's phenomenally successful series. 

Directed by Potter stalwart David Yates, Deathly Hallows is set to be the dark, gloomy, thrilling final movie that people dared to hope for, building up to the climactic battle of Hogwarts, which will probably end up taking up most of the film's second part.

Still unsure why there's so much buzz around one boy wizard? Check out the trailer over here (there's even a pretty poster of a building on fire), and readjust your wand settings. Then, if you fancy the chance to win a seat at the premiere, head over to the official Harry Potter UK Facebook Page. Or just watch Potter Puppet Pals for the 100th time - that won't win you the ticket, but it will keep that Potter high going.

Harry Potter and the Deathly Hallows (Part 1) hits cinemas on Friday 19th November. Part 2 will arrive on Friday 15th July 2011. You can start counting down to that one in your own spare time.

Yes, you're in with a chance to win tickets to the World Premiere of Inception in London. All you have to do is track down The Extractor (your average shady man-with-a-briefcase type) as he travels around the UK looking suspicious and Inceptiony. Yes, that's a word.

Head over the Inception page on Facebook and follow the clues for his location and you can win a pair of tickets, plus travel and accommodation. Ooo, fancy. The nationwide hunt started last Wednesday, with clues appearing online. Can you hunt him down? If you do, just tell him the code and you'll bag the prize. Simply say the words "My mind is the scene of the crime" - it's as easy as being a Russian spy!

The clues get posted on Facebook as The Extractor visits the following places:

Saturday 3rd July
Manchester

Monday 5th July
Liverpool

Tuesday 6th July
Birmingham

Wednesday 7th July
Bristol

Thursday 8th July
London
