The film's title "The Waiting Game" is only mentioned once throughout the entire film.
The character Leigh was designed to be able to change genders if the right actor couldn't be found. Possible candidates for this role included Samuel Boys, Emily Smith, Kyle Tompsett, Samuel Beard and Timothy David Mitchell himself. Eventually, Alec K won the role.
Timothy David Mitchell cites the Dogme 95 manifesto (as well as various films by Lars von Trier) as influences on the film's style, despite nearly all the rules of the manifesto being broken at some point. Mitchell even wanted to put a small tongue-in-cheek "confession" of the broken rules for the manifesto, but decided to scrap the idea as the production went along when he realised that he had broken more rules than he had aimed for.
Originally, it was planned to have actors audition with excerpts from other films, including Lars von Trier's Antichrist (2009), David Fincher's The Social Network (2010) and Quentin Tarantino's Pulp Fiction (1994). This idea was scrapped after the ending change due to the film's content and subject matter and the final script was sent out to all actors to read so they knew exactly what they were getting into.
This is the first feature film by Timothy David Mitchell not to include end credits. All of the credits are shown at the beginning of the film during the opening title sequence just like the earlier films used to do. Mitchell had wanted to try this technique out for quite a while, and decided to employ this technique here in order to make the audience leave the film in a heightened state of shock and suspence, as he believes end credits would give the audience a chance to calm down again as they left the cinema.
