Filming of funny kinda guy began in January 2002, when filmmaker Travis Reeves first heard that his friend Simon de Voil had decided to take testosterone. Recognising this rare opportunity, Travis immediately bought a MiniDV camera and started to record his friend's transition.

After eight months of filming, key events in Simon's transition had been captured, and what began essentially as a small-scale personal project had grown into a feature production. Producer Wendy Griffin, with whom Travis had worked previously on drama projects, brought independent company Sprocketeers to the production. Editor Bert Eeles and dubbing mixer John L Cobban completed the creative team.

Production finance from the National Lottery was secured through funding organisation Scottish Screen, enabling a first phase of editing to begin, followed by the second phase of shooting in Brisbane in April 2003, and then final weeks of editing and post-production sound. In February 2004, two years after the first scenes were shot, the film was completed.
