"The music of Tangerine Dream was an early and major inspiration for the film of Sorcerer.
I first heard the Tangerine Dream while in Munich for the opening of The Exorcist.
Had I heard them sooner I would have asked them to score that film.
A year later, we met in Paris. I told them the story of the film and gave them a script.
I took more than two years to make Sorcerer.
One day in the middle of a primaeval forest in the Dominican Republic, about six months into shooting, a tape arrived from The Dream, contains ninety minutes of musical impressions. It is from this tape that the film has been scored, though the musicians had not then nor even now as this is written seen any of the footage.
Yet somehow they were able to capture and enhance every nuance of each moment where their music is heard.
The film and the score are inseparable." — William Friedkin
