The filmmaker decided to change the actor playing an anonymous drug dealer character because the original actor, Frank Dunn, looked too young for the role. A 19-year-old actor, Christopher McDonagh, was chosen instead because he had a more mature appearance that better fit the character. Some footage was deemed unusable - shop footage didn't seem sinister enough and a scene with dark lighting made the characters' faces hard to see. The filmmaker plans to not show the male characters' faces to add mystery and portray them as more sinister figures.
