I have to say, when I met Mr. Mee last summer while zipping past the house - which is really right there in the zoo, I didn't immediately think "Matt Damon" when he mentioned they were doing the movie. Still, Damon's a good actor, so I'm sure he can pull it off, and will be able sound British to us Americans, anyway.
It's hard to imagine that the area can get that crazy with tourists, given the Devon walls, which make it hard to get to - and can't be moved!
I decided to visit the zoo last summer after reading the book and then realized after I got there that I had been there a few years ago. It seemed quite a bit lighter this time, although my favorite thing is still watching the otters get fed.
