Book adaptations to the big screen have always been some of the most interesting ways to make good films. And probably the most rewarding as well. Though we believe that a book it’s always better than the movie, that doesn’t mean that book-to-film adaptations aren’t good.

Quite contrary, they can be very good, as Hollywood has proved many times.

And if you combine a bestselling book – preferably one which depicts a marvelous fantasy world – with some of the best actors Hollywood has to offer and add in some jaw-dropping special effects, the result is sure to astonish millions of people around the world and bring in some great revenues.
