This document provides details on the pre-production planning for a horror/slasher film about two sisters defending themselves from an intruder in their home. It outlines that the film will take place entirely over one night in a single location (their house) to create a trapped feeling. Costumes will include fake knives and sourced wardrobes to dress the sisters in mourning clothes and the intruder in a hooded mask. Filming will occur on a weekend in the school holidays when actors are available to minimize scheduling complications of the small production shooting in a single location.
