After all, it is not where one washes one's neck that counts but where one moistens one's throat.
I think film writing, you're thinking in pictures, and stage writing, you're thinking in dialogue. In film writing, it's also, you only get so many words, so everything has to earn its place in a really economical way. I think for stage writing, you have more leeway.
In fact, words are well adapted for description and the arousing of emotion, but for many kinds of precise thought other symbols are much better.
