Well, at least you can get the book cheap!

Sadly, I never saw the film. But I read the book because the cover looks just like a cat I used to have.
The book has lots of pictures and made an old woman like me cry buckets.
What a wonderful story. I don't know if I would want to watch the film, though.
I'd be too sad, probably.
