On September 22, 2006, it was revealed Tony Leondis would direct the feature. He got onboard due to sharing McKenna's interest in horror films and sardonic sense of humor, in addition to being intro film noir and German Expressionism works; Leondis helped the writer in developing the setting's backstory, a more complicated process than McKenna predicted that required collaboration from not just the director but also the actors and producers. Leondis explained, "My goal was to take familiar monster motifs and rearrange them in a surprisingly fun way to evoke the memories that people have of classic monster movies. Something familiar enough to connect to, but at the same time fresh and unexpected so that it became a fun ride – and maybe makes them think a little along the way."
