Okay, I’ll try to make this a good one. I’ve also decided that I’m not going to push myself into theme analysis the Blake Snyder way unless something clear occurs to me.
Opening image: Charlie heading over to his friend’s house, singing to himself, but he’s alone – and for a few minutes we don’t really get a good look at his nose.
Setup: The sports gear fencing scene with the two jerks, drops in on Dixie at the Cafe, and goes to the fire hall.
Catalyst: Roxanne gets locked out of her house, Charlie goes to help her, and he is drawn to her when she starts talking about the stars. The next day, Chris moves to town and starts working with the firefighters.
Debate: Roxanne meets Chris, and likes him, Chris thinks that she’s pretty and gets too worked up to talk to her. Roxanne comes to Charlie to talk about the guy that she likes, and he misunderstands at first. Roxanne asks him to talk to Chris for her.
Break into two: Charlie decides to help Chris and Roxanne.
B story: I’m not sure what this is, unless it’s the plot arc with Charlie and the incompetent firemen.
Fun and games: Fireman scenes, some of the bit with Charlie playing Cyrano – and the scene in the bar when he’s coming up with 20 good nose jokes.
Midpoint: Chris asks Charlie to help him write a letter to Roxanne, but he’s hopeless at romance, and Charlie gets inspired and writes it himself.
Bad guys close in: Roxanne is falling for Chris, but keeps quoting the letter from Charlie. Chris screws up the first date with Roxanne.
All is lost: Charlie seduces Roxanne from the darkness, she still thinks it’s Chris and invites him up.
Dark night of the soul: Roxanne finds out the truth and fights with Charlie, both of them saying bad things about the other and about his nose.
Break into three: Charlie smells the fire and leads the fire truck to it.
Finale: The firefighters competently save the town, Charlie’s a hero. He becomes less sensitive about his nose, and Roxanne tells him that she loves him for it, not in spite of it.
Final image: Roxanne manages to figure out a way to kiss Charlie without getting poked in the face, they go to her house but are locked out again. Charlie has the key this time, though – and a comet streaks by overhead.
