As with Uncle, Elliot chose a minimalist approach and sparse narration to drive a very simple remembrance of a childhood relationship he had with his cousin (based on his real-life cousin), who has cerebral palsy. Like Uncle, Cousin has a greyscale palette but was shot on colour stock. This film was shot in a small storage unit in the outer suburb of Moorabin in Melbourne at a facility owned by his father.
The director's approach to filmmaking is similar to that of his previous work, "Uncle." The film shares stylistic elements with "Uncle," including its minimalist narrative style and use of a grayscale palette. It was filmed in a small storage unit in Moorabin, an outer suburb of Melbourne, owned by the filmmaker's father.
