Roger MacDougall
Playwright Roger MacDougall (2 August 1910 – 27 May 1993) began writing the occasional screenplay in the late 30s, working both alone and in collaboration with others. Most of his plays were produced during the 50s. As a screenwriter, his best-known films are The Man in the White Suit (for which he received a 1952 Academy Award nomination) and The Mouse That Roared. He was a cousin of Alexander Mackendrick.
During the 1950's he was diagnosed with multiple sclerosis which eventually resulted in significant disability. Through disillusionment with orthodox medical treatments at the time, he developed a diet, loosely based on a paleolithic diet, that apparently returned him to good health and sustained remission. Following this experience, he published a pamphlet describing his diet intended to help other patients to achieve similar results. This diet produced positive results in other patients, though success was not universal.
