One secret is to unpolish your screenplay. You’ve smoothed things out enough to have everything finally slide into place, and provide your readers with a pleasant reading experience. But now you’ve got to strip some of that polish off and expose some jagged edges. Something for the reader to trip over and get a busted lip.
I’ve talked before about the gutpunch scene: these happen mostly in dramas—the Oscar-worthy scene where the subtext falls away and the actors finally get to wallop each other with all of their suppressed emotions.
But for other genres, you need to go even further: For comedy, action, and thriller, you need the OMFG scene. Think of the trailer. What’s the one moment that will make people need to see this movie? What ceiling are you going to smash through that nobody else has even touched?
- Comedy: American Pie famously revived a dead genre by showing a kid violating a pie in the trailer (a gag so funny they named the movie after it) and I mentioned before that I saw The Campaign because Will Farrell’s character punched a baby in the trailer. I literally thought, “okay, this isn’t going to play it safe, this is going to go for big laughs.”
- Thriller: People flocked to see The Grey because the trailer implied that Liam Neeson was going to get in a fistfight with a wolf (…only to discover that the movie ends with his preparation for that fight. They did shoot the actual fight, but it looked too silly. Because of course it did.).
- Action: Everybody went out and saw Independence Day because of the shot where they blew up the White House. Now the same director is using the same lure a second time, but I suspect he’ll have diminishing returns. An OMFG moment requires the audience to say “I can’t believe they went there!” But if you’ve done it before, they can believe it.
Obviously, it’s easy to get cynical about such scenes (When writing a broad comedy, I watched 20 recent comedy trailers and jotted down the biggest laugh in each one: a shocking number involved raccoon attacks, or head injuries, or both) but these scenes actually can make your script better. Your story needs a reason to exist. People choose these three genres in order to get juiced up, so deliver the juice.
But wait, you say, I don’t want to write an outrageous, over the top movie, I want to do a muted, ‘70s style, thoughtful movie: Oh, you mean like Annie Hall?
Or The Godfather?
EDITED TO ADD: Hmm... I just realized, looking at those two clips and the image above them, that they all involve casually destroying another person's most prized possession. Obviously, that's a good way to start. This goes back to the idea that people hate stuff.
EDITED AGAIN: This used to be called the OMFG scene, but I decided that sounded too dated, so I changed it to “Holy Crap!”
