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.
It's hard enough to get any movie made, and when you take on these tough genres - and I've done it a couple times - it just makes the whole struggle more.
