Actor Heath Ledger has been found dead at the age of 28 at his home in New York.
Heath grew up in Perth, Australia, and one of his earliest screen appearances was on TV soap Home and Away.
But he quickly went on to bigger things, starring in blockbusters like 10 Things I Hate About You, and as William Thatcher in A Knight's Tale.
He went on to play lots of different characters, taking on some serious roles and some more light-hearted.
It was during filming on a big blockbuster movie he met his girlfriend Michelle Williams and had a two-year-old daughter called Matilda. But sadly, the couple split up last year.
Heath had just finished playing The Joker in the new Batman film The Dark Knight, which hasn't been released in Britain yet.
When he died, Heath was half-way through filming a new movie, and was thought of as one of Hollywood's brightest young actors.
Heath's family, friends and other actors have been saying how sad they are about his death, and flowers have been left outside the apartment where he died in New York.
