According to someone who's written a review on Amazon (well, if it appears anywhere on the internet it must be true!) Gideon Defoe is working with Aardman Animations (who did Wallace & Gromit and Chicken Run) to turn the first two pirate books in to a film. I had a quick look at Aardman's site, but it's one of those weird sites where it's impossible to actually find anything out.
