Scene tonic for stories? Why would you need it?
How many times have we come across this scenario? Our hero needs to uncover information about someone, or something. He googles it, goes to his local library, zips through old newspapers, records.
In his book, Your Screenplay Sucks, William M. Akers suggests the only memorable thing about such scenes would be if the computer blew up in his face, or a library shelf collapsed and hit him on the head.
Staring at computer screens, or paging through records makes for dull scenes. It is much better to have your character corner a grumpy librarian and try to solicit the information from her, or try to bribe a shady cop, or talk to the local priest.
Now, you not only get the information necessary to drive your story forward, but you layer the scene with tension or humor via the subtext rooted in the reluctant informant. The result is a richer, more dramatic and entertaining event. Even if your character fails to extract the information, he generates interest.
In Chinatown, Jack Nicholson has to deal with a sour, officious clerk. He asks if he can check out a book of records from the facility and is told this is not a lending library. He then asks the clerk for a ruler. “A ruler?” the man snarks back. It’s to help keep his eyes focused on the lines of text, Nicholson replies. The clerk slaps a ruler on the desk in front of him. Nicholson grabs it and hurries back to the records book. He coughs loudly, simultaneously tearing a page from the book with the aid of the ruler.
In the example above, there is no scene tonic needed—not only does the hero get the information he needs, he makes a fool of the unlikable clerk.
Interaction between characters is always superior to eyeballing screens, or flipping through pages in a book. Scour your story for such scenes and try to inject human conflict into them, even if that conflict is small. Your scenes will be better for it.
A scene tonic is needed if information gathering becomes boring. Extracting information from another character is better than extracting it from the internet or a book. At the very least, have your hero try to convince others to help him acquire it.
