The monologues which comprise the film were intentionally written after the entire film was shot. Each shoot day consisted of showing up at the beach and Cody Clarke coming up with scenarios for the characters to perform, with all dialogue left up to them, as it would not be heard. After all the shoot days, a rough cut of the film was constructed of all the best shots and takes, and Cody wrote the monologues to that footage.
The first 'shark movie' without a shark in it.
All of the shark facts rattled off by the main character are true, or close to true.
One of Jules Roscoe's favorite chunks of monologue is the 'pea soup' part, despite not liking pea soup herself.
Cody Clarke watched over 60 shark movies during the making of this film, only a couple of them documentaries. He did this to get into the head of the main character, and also to familiarize himself with what had come before. He also felt it to be beneficial for the project on a karmic level.
