Dark Knight: The Imax Experience previews on Thursday July 24 - and you could be among the first to see it.

We're giving away three pairs of tickets to the preview today.

And the Gotham City thrills can't get any bigger!

The IMAX screen at Thinktank as high as a five-storey building and as wide as four buses.

What's more, you're surrounded by 42 speakers of state-of-the-art digital surround sound, putting you in the movie.

"In continuing the story of such a great icon I'm thrilled to be able to expand the scope of the film, not just in terms of its story, but in giving Batman and the Joker the largest possible canvas on which to face off," says director Christopher Nolan.

"No existing technology compares with the IMAX format in terms of its ability to throw the audience into the action, and we're very proud and excited to use this technology in a way that no-one has before!"
