Watch Narnia trailer in high def

If you've got an Xbox 360.

Microsoft has signed a deal with Walt Disney Pictures that will let Xbox 360 download the trailer for The Chronicles of Narnia: The Lion, The Witch and The Wardrobe.

And what's more, it's presented in glorious high definition, so if you've got a HD telly it'll be just like actually being in Narnia. Possibly.

The trailer, which will be available via the Xbox Live Marketplace, will feature highlights from the film that's set to top the box office charts this Christmas. For those who are unfamiliar with the story, it's about some kids, a lion, a witch and a wardrobe, and - spoiler alert - it all turns out all right in the end.

The Chronicles of Narnia: The Lion, The Witch and The Wardrobe hits UK cinemas today. The videogame tie-in is out PC, PS2, GBA and Nintendo DS.
