John Kassab is a multi award winning Australian screen storyteller and law school dropout.

John's career launched in 2010 as the sound designer of Deeper Than Yesterday (2009) which won 3 prizes at Cannes and the Sundance International Grand Jury Prize. That same year, John was the recipient of a Winston Churchill Fellowship and embarked on an intentional tour to research the latest developments in sound post-production. This experience saw him meeting with 40+ voting members of the academy where he helped to successfully campaign his latest sound project The Lost Thing to win an Oscar.

In 2011, John relocated to the US and began producing independent films in Los Angeles, New York, Massachusetts, Baltimore and Atlanta. Throughout his producing career, his focus has been to provide a platform to underrepresented voices. His debut feature documentary 12 O’Clock Boys (2014) told the story of an African American boy in Baltimore who dreamed of joining the city's notorious illegal bike gang. It premiered at SXSW to considerable acclaim, a theatrical release, ending up on Showtime in the US and SBS in Australia. It has been adapted into the Sundance Special Jury Prize winning film Charm City Kings (2021; HBO) by Oscar winner Barry Jenkins (Moonlight).

In 2015, John returned to Australia to produce and direct the web series Renaissance Woman for comedian Hannah Gadsby. In 2016, John followed this by co-producing the Spanish language thriller Debris, a film about undocumented Mexican workers in LA whose organs are harvested for the medical black market. It premiered at Telluride Film Festival in 2017 and qualified for Oscar consideration in 2018 after winning numerous top prizes at festivals. 'Debris' is now available on HBO Go.

in 2017, John produced They Wait for Us, a psychedelic science fiction told from the perspective of a Chinese night shift worker at an upmarket British palliative care facility. It premiered at Fantasia Film Festival and has received multiple prizes and nominations. John continues to work in sound design. His latest tracks can be heard on the animated paper stop motion The Grave of St Oran (narrated by and based on a poem by Neil Gaiman) and Morgana, a feature documentary about the famed Australian middle-aged feminist porn star.

Since returning to Australia in 2018, John has turned his attention to screenwriting and has been developing TV and feature film projects. In 2020 he served a term as president of diversity film education and outreach organisation Cinespace, Inc before joining Princess Pictures as a producer where he has worked on shows for Disney +, ABC, SBS, Amazon and Audible.

In 2023, John left Princess to start AMON:FILMS in the Macedon Ranges where he is developing a number of scripted and factual projects as a producer, writer and director starting with a documentary feature film set in the US (to be completed in 2024).
