Sometimes, Holdren would add scenes/actors that were not scripted in order to keep Waters guessing, because like his character, Waters should never have known everything. Rehearsals consisted of movement exercises and characterization, and Waters came up with most of his character's history and was granted several opportunities for improvisation. However, these efforts weren't just for Waters' sake.

The efforts to preserve this air of mystery was also an experience for the crew, because it became a novelty for them to secretly move actors around a location to keep them from seeing each other, and other such fun. As a result, everyone had their own idea or curiosity of what this movie was about. While Holdren dosen't always use these techniques in his directing, if there was ever a project where this type of directorial style was appropriate, this was it.
