I love that book! And I love the title, actually. It's supposed to be ironic, because it sums up many of the main problems of the book: that what matters most is actually silent and very far away.
However, I doubt I'll see the movie. The book is great because it delves into people's thoughts, and I doubt it will translate well into actions necessary to make a movie. Also, I definitely didn't picture the mom and dad to be anything like Sandra Bullock and Tom Hanks at all, so I would probably find it weird.
