Matt lives with his careless roommates Amy and Kev in a share house in the inner-west suburbs of Sydney. When a sinister mould infestation takes root in their abode, Matt is quick to suspect that it may have more harmful effects. Taking initiative despite still remaining weary of the mould, Matt attempts to clean it off, however he soon realises that this endeavour may be harder than he thought.

Matt tests alternate cleaning methods and starts to notice that both Kev and Amy have become ‘infected’ when they start acing out of character. As Matt becomes certain that the mould has not only caused his roommates’ mind-controlled hypnosis, but may also be putting their lives at risk, he soon becomes even more determined to eradicate it before it’s too late.



The Mould on the Wall  takes much inspiration from my experience living as a tenant in Sydney during recent extreme weather events, such as La Niña. I have experienced a number of summers of torrential rain, and this has constantly produced growths of black mould where I reside, in addition to the ominous potential of it provoking serious respiratory illness.

I wanted to recreate this experience as I have found it to be a very common one amongst friends, families and colleagues who rent, and further combine this experience with the dynamic interactions of living with roommates. It seemed only natural to fuse this experience with the thriller or horror genre, as at times, I'm sure many of us have felt that the fungi we see within the world has a scarily supernatural element to it. Upon discovery of the Ophiocordyceps Unilateralis fungi, I took inspiration in how it mind-controls (and eventually kills) bullants in some forests around the world. Imagining what it might be like if black mould in the home worked like 'Cordyceps' did, was an exciting concept to explore when conceptualising the project.


Much of the cinematic inspiration of the film stems from the work of many 'post-horror' practitioners, including Ari Aster, Robert Eggers, Jordan Peele, Jennifer Kent, and Julia Ducournau. I absolutley love how these filmmakers prioritise the psychological to generate horror, as well as leave the viewer with a satisfying yet open ending, and I just had to attempt to implement these features into the final film. I also wanted to fuse this modern take on the horror genre with elements of the comedy, with the film attempting to take into account the absurd and the exaggerated, in order to provide a sense of comic relief amongst this common household problem.

A huge thank you to the cast & crew of the film, I could not have made this (and had so much fun making it) without each of your talents, motivation, and energy.
