Leon is a self-taught London based filmmaker. He has a reputation for being unflinchingly honest in addressing racism and injustice. His short documentary That's Not Ours premiered at Sheffield Doc / Fest in 2018. The film is a deeply personal exploration of racist media stereotypes and the consequences faced by young black men and boys as a result all framed around Leon's younger brother Ethan - an innocent victim of knife crime. Leon is passionate about telling stories that challenge stereotypes and change perceptions.
