For his performance in this movie, Geoffrey Rush became the first actor to win Best Actor at the Academy Awards, Screen Actors Guild Awards, BAFTA Awards and Critics' Choice Awards, as well as Best Actor-Drama at the Golden Globe Awards.
According to Scott Hicks, the title "Shine" was inspired by Pink Floyd's track "Shine on you crazy diamond", written in tribute to their first band leader Syd Barrett, another musical genius with mental illness.
Dustin Hoffman expressed interest in playing David Helfgott, as his music and life story have moved him. He had previously portrayed a savant in Rain Man (1988).
