Other major composers and record-producers include George Martin, Bill Conti, Michael Kamen, Marvin Hamlisch, Éric Serra, Thomas Newman and Hans Zimmer. Each of these composed for only one Bond film, with the exception of Newman. The departures from John Barry had various causes; sometimes Barry declined in order to avoid paying double income tax—US and UK. Barry died in 2011. Sometimes the director of a Bond film had worked with the composer of his choice on other films — the latter happened to David Arnold with "Skyfall" and "Spectre".
