It was on the set of his first major film, "The Man Who Fell to Earth", that Bowie began writing a pseudo-autobiography called "The Return of the Thin White Duke". He was also composing music on the understanding that he was to provide the picture's soundtrack, though this would not come to fruition. (At Bowie's recommendation, John Phillips of the Mamas and the Papas would write and produce all the original music for the film instead.) Director Nicolas Roeg warned the star that the part of Thomas Jerome Newton would likely remain with him for some time after production completed. With Roeg's agreement, Bowie developed his own look for the film, and this carried through to his public image and onto two album covers over the next twelve months, as did Newton's air of fragility and aloofness.
