I've just had the great pleasure of watching the 1962 film of "To Kill a Mockingbird", to assess how it conforms to and differs from the book. I did the same with the two film versions of "Of Mice and Men" last year.
Interesting exercise; partly because the films are of their time, more so than the novels. Censorship and cinematic taboos influence directors' scope and values. And there are some types of writing which you can't really translate on to film. Some things must get lost on the way; do the important ones get preserved?
Some time quite soon I'm going to finish reading Virginia Woolf's "Mrs Dalloway" and then watch the film of that- which must have been quite a challenge to make, I imagine.
Does thinking cinematically make us better writers? What do you think?
