Act 2. Still posing me problems. But I know what happens in act 3. I know where and how the hero winds up in act 3 so I'm remembering a little advice a few screenwriting teachers and gurus have offered before and that's to start writing backwards, from the points I know about. Odd, I know, but it makes sense.
The destination is all ready and I know exactly how things end. It's just getting him to the points where he will have to act on his previous experience and where everything is a consequence of what has come before. These are the themes and ideas resolved. It's like writing an essay when you are asked to explain an idea or theory and have to read up and learn about how these things occur.
The big fear is that act 2 will be boring. I need to create situations where the hero is tested further while not testing the audience's patience. I need to keep an old phrase in mind through all of it: What will happen next?
So everything in the second act will have to play a part in creating the climax while still maintaining excitement and keep steadily building the odds.
