Ledger died on 22 January 2008 as a result of an accidental overdose of medications. A few months before his death, Ledger had finished filming his role as the Joker in The Dark Knight, with his performance earning him universal acclaim and popularity, receiving numerous posthumous awards including the Academy Award for Best Supporting Actor, the Golden Globe Award for Best Supporting Actor, and the BAFTA Award for Best Supporting Actor. His final role in The Imaginarium of Doctor Parnassus was released posthumously in 2009. Heath Andrew Ledger was born on 4 April 1979, in Perth, Western Australia, to Sally Ramshaw, a French teacher, and Kim Ledger, a racing car driver and mining engineer whose family established and owned the Ledger Engineering Foundry. The Sir Frank Ledger Charitable Trust is named after his great-grandfather. He had English, Irish, and Scottish ancestry. Ledger attended Mary's Mount Primary School in Gooseberry Hill,  and later Guildford Grammar School, where he had his first acting experiences, starring in a school production as Peter Pan at age ten. His parents separated when he was ten and divorced when he was eleven. Ledger's older sister Kate, an actress and later a publicist, to whom he was very close, inspired his acting on stage, and his love of Gene Kelly inspired his successful choreography, leading to Guildford Grammar's 60-member team's "first all-boy victory" at the Rock Eisteddfod Challenge. Ledger's two half-sisters are Ashleigh Bell (b. 1990), his mother's daughter with her second husband Roger Bell, and Olivia Ledger (b. 1996), his father's daughter with his second wife Emma Brown. After sitting for early graduation exams at age 16 to get his diploma, Ledger left school to pursue an acting career. With Trevor DiCarlo, his best friend since the age of three, Ledger drove across Australia from Perth to Sydney, returning to Perth to take a small role in Clowning Around (1992), the first part of a two-part television series, and to work on the TV series Sweat (1996), in which he played a cyclist. From 1993 to 1997, Ledger also had parts in the Perth television series Ship to Shore (1993); Ledger also had parts in the short-lived Fox Broadcasting Company fantasy-drama Roar (1997); in Home and Away (1997), one of Australia's most successful television shows; and in the Australian film Blackrock (1997), his feature film debut. In 1999, he starred in the teen comedy 10 Things I Hate About You and in the acclaimed Australian crime film Two Hands, directed by Gregor Jordan.
