As part of the BBC's Sound of Cinema season, Tom Service talks to ten-time Academy Award nominee James Horner. Horner was born in Los Angeles but spent his early years in London and studied at the Royal College of Music before returning to California to pursue a doctorate in composition. Having initially intended composing concert music he fell into the film industry more or less by accident. His award winning collaboration with James Cameron has spanned three decades, from Aliens in 1986 to the biggest selling soundtrack of all time Titanic, and most recently 2009's Avatar, and he has also regularly worked with Ron Howard (A Beautiful Mind, Apollo 13), and Mel Gibson (Braveheart, Apocalypto).
