Good luck if you can get it though, my Realplayer is telling me there's a general error when trying to download it, however...

The BBC have an exclusive clip over and above the trailer (which I saw on telly last night and was most mouth watering).

In the clip, which follows the release of the movie trailer in March, Gromit is chased in an airborne dog fight.

You can supposedly get the clip from the main BBC Movie site, you should see the link on the top right of the page under current hot links. Good luck, and if you get it, as usual, review it here.
