Watership Down remains one my top three favorite books, ever since I first read at 16 nearly forty years ago. Loved the animated film also. Never could make it to the end of The Plague Dogs, either the book or the animated film. Just too, too depressing. Which I guess is a testament to how well written the story was. Think I'm going to give Watership a re-read in his honor.
Yeah, just try to watch that clip without tearing up....I can't.
