Moment of Genius: Dan O'Bannon talking about writing a screenplay, when he has a problem with exposition where it seems forced, cut it . Keep the dialogue true to the characters in their situation. It's important that he knows what's happening as a writer, and it's important that the filmmakers know it, but the characters do not have to say it. I think that's a lot harder to do in practice, but what a wonderful bit of breakthrough for writing, at least for me.
