To mark the release of the eagerly-awaited Gone Girl in cinemas on Thursday October 2, we're giving you the chance to win some movie goodie bags.

Gone Girl - directed by David Fincher and based upon the global bestseller by Gillian Flynn - unearths the secrets at the heart of a modern marriage. 

On the occasion of his fifth wedding anniversary, Nick Dunne (Ben Affleck) reports that his beautiful wife, Amy (Rosamund Pike), has gone missing. 

Under pressure from the police and growing media frenzy, Nick's portrait of a blissful union begins to crumble. 

Soon his lies, deceits and strange behaviour have everyone asking the same dark question: Did Nick Dunne kill his wife?

To be in with a chance of winning a goodie bag, just answer this question:
