The Insider is a 1999 American drama film directed by Michael Mann. The film stars Al Pacino and Russell Crowe, with supporting actors including Christopher Plummer, Bruce McGill, Diane Venora and Michael Gambon. It was nominated for 7 Academy Awards and 5 Golden Globe Awards. A fictionalized account of a true story, it is based on the 60 Minutes segment about Jeffrey Wigand, a whistleblower in the tobacco industry, covering the personal struggles of him and CBS producer Lowell Bergman as they defend his testimony against efforts to discredit and suppress it by CBS and Wigand's former employer.

Pieter Bourke and Lisa Gerrard composed the filmscore. Like all Mann’s movies, the film gets much of its tension and suspense from the acclaimed director’s bold use of music. ‘I like music that has an active role to play’, says Mann. ‘I am not really interested in music that’s merely complementary. I like it when I can redefine something. Music can redefine the moment to the point that one could turn an emotional reaction inside out with a cue.’

Mann had originally intended for Bourke and Gerrard to compose three or four cues for the film. ‘Their work was so spectacular that they became the composers for the picture’, says Mann, who was so pleased he invited the pair to move to Los Angeles and work with him closely on finishing the music for the movie. ‘Lisa and Pieter throw themselves into projects with total artistic commitment. It’s been a great, great expereince working with them. I listen to their music and I’m transported. Hopefully it does that to you.’

Pieter and Lisa’s score received a 2000 Golden Globe Award Nomination for Best Original Score.
