George Miller (born 3 March 1945) is an Australian film director, screenwriter, producer, and former medical doctor. He is most well known for his cult Mad Max trilogy, but has been involved in a wide range of projects, including the Oscar-winning Happy Feet and Babe film series. Miller is the older brother of producer Bill Miller. He is also co-founder of the production houses Dr. D Studios and Kennedy Miller Mitchell, formerly known as Kennedy Miller. Miller was born in Brisbane, Queensland, to Greek immigrant parents: Dimitri (Jim) Castrisios Miliotis and Angela Balson. Dimitri Miliotis was from the Greek island of Kythira and he anglicised his surname to Miller when he emigrated to Australia; the Balson family were Greek refugees from Anatolia. The couple married and settled in Chinchilla and had four sons. The first two were the non-identical twins George and John, and later, Chris and Bill Miller arrived. George attended Ipswich Grammar School and later Sydney Boys High School, then studied medicine at the University of New South Wales with his twin brother John.
