John Cleese on Creativity (by bedroomstudiotube)
This lecture by John Clesse has some very important implications both for you as a writer but also for your characters, with wider implications for what they can get away with in their behavior in combat situations.(Though he doesn’t discuss that in the video.)
The idea is this: combat happens when your characters in the Closed mode, it’s a high pressure environment where your characters need to make decisions immediately and decisively with no room for error or doubt. Humor in those situations is a luxury. It pushes the character into a more contemplative mode, the Open mode. It gets them thinking when they don’t have the time to be thinking( a distraction) in a fight.
Trash talking, joking, and one liners can happen before and after a fight, but not during. The only sort of trash talk that can occur during is the sort where your character doesn’t have to stop and think about it, but even then, remember that talking is not a free action. It requires breath, takes oxygen that should be going to your character’s muscles, while both loosening and relaxing the jaw which leaves your character more open to a knockout blow or biting their own tongue when they get hit.
Always dedicate points in your story for the times when your characters are capable of cracking jokes to release the tension (before and after) and when they need to buckle down for work (the fight itself).
So, watch the video, it’s useful and informative plus it’s John Cleese. It’s hilarious.
