The love I have for The Wind in the Willows cannot be overstated. I can't begin to guess how many times I've read it, and it still makes me laugh right out loud, and then makes me tear up and sniffle like a little boy.
My children love this book too, especially the younger, who can't get enough of little animals in velvet waistcoats acting like humans in all seriousness: she is completely dedicated to the entire Beatrix Potter oeuvre, as well.
Several times people have tried to adapt Wind In The Willows to film, with varying degrees of success. And normally I don't really hold with adaptations, only because people feel that, once they've seen It, they know all about It and don't need to read It. But this one is really, really good - so funny - and you should try it sometime this winter (it's a perfect winter movie - also it's a perfect summer movie). But you do have to give it a chance - the makeup can be a little startling at first, but once you enter into the spirit of the thing it's universally charming. The intervention scene, when Toad repents of his motorcar behaviour, is hilarious.
A little preview!
