I'm on my 4th script and have the same problem. I have an interesting concept. Visualize the character's motivation and conflict and the ultimate resolution to that conflict.
I get stuck in the middle. Every outline/script feels like it's dragging in the middle. I always seem to be about 20 pages short and fill it in with the same old conflict in a different form. Yes it progresses, but it feels fluffy in parts.
Any tricks you know to creatively add extra meat to your story, that raise the stakes for the hero leading to the ultimate conflict?
Or is it something as silly as using more "baby conflicts" that lead the hero to the ultimate jumbo conflict (lose the girl for good).
It feels like I rush to the final conflict and come up 20 pages short every time.
What you really need to do is to take a step back and forget about the second act altogether.
It's very easy to get bogged down in it and to forget that, in large measure, the second act doesn't really matter.
Why?
Because, in structural terms, every second act is exactly the same.
The story premise, which is (at least potentially) special, is set up in the first act.
The resolution, which is also (at least potentially) special, is resolved in the last act.
The second act, whatever the story, can always be reduced to the same thing. In fact, when I used to write coverage and you had to jam a lot of story into a couple pages I found that the easiest way to do was to simply cut out the entire second act, or at any rate reduce it down to a few lines.
That's because you can really express every second act in three words.
"Various complications ensue."
That's it. That's all that's going to happen in the second. Various complications.
At the end of the Second Act you're going to end up with a really terrible complication -- the apparently insoluble problem.
You bring your protagonist to his lowest point. He can't go on. There's no way forward.
But wait. Yes, there is.
Because you've set up some baggage or other that he's been hauling along with him for the whole movie -- and it's that baggage that, unbenownst to him (and maybe even to us, though you've set it up) that's keeping him from moving forward.
Ah hah! He realizes it. And he frees himself of whatever that baggage is.
And he advances. He moves forward and overcomes the final obstacle and triumphs -- or, if you're one of those downbeat writers, he has the opportunity to do so but fails to do it and you end up with a downbeat bummer of an ending (or a foreign film).
Here's the conventional wisdom -- which is generally correct.
If you've got a problem with your third act, your real problem is most likely in your first act -- because that is where the ground work for your third act is set up.
A story, in a sense, is like a thesis -- a person is faced with a certain kind of problem -- that problem has an external aspect -- aliens, hostage takers, cheating boyfriends, and an internal aspect -- some quality that the protagonist has or lacks that is reflected by all of those external goings-on.
He has to make certain decisions to solve that problem -- ostensibly the external problem. But, in fact, the real problem that needs solving is the internal problem. The solution to the external problem lies in resolving the internal problem.
And the decisions that he makes, or fails to make relates to that internal issue and the external problems that he confronts are designed to force him to come to terms with those very same internal issues.
The coward is forced to face his cowardice.
Someone who is insecure is put in a position wher he has to face his insecurities.
A liar must tell the truth.
The external story both drives and is driven by the *internal* story of the protagonist, forcing him, ultimately, to that "moment of truth" -- the apparently insoluble problem.
Insoluble, unless he faces that fundamental internal issue.
So what you really need to do is to step back -- get away from the specific story beats and address that larger question of what it is that is driving your story as a whole, because that is going to answer the question of the big story beats -- the premise, the mid-second act turning point, the end of second act "insoluble problem" -- and the ultimate resolution.
