In one scene, Hush is chasing Channtelle down a slope, but because it had been raining all morning the actor playing Hush (Peter Coster) slipped over skidding 30 feet on his backside. Fortunately he was unhurt.
In the script the film ended at around 3 minutes but because the improv was so good the producer and editors decided to keep it in the final cut.
Hush was one of fifteen short scripts the writer Peter Coster wrote in one day. The idea was that over the course one weekend the three friends Peter, Paul and Rami would film as many of them as possible. Unfortunately because of the bad weather only this one was filmed.
