John Lee Mahin (August 23, 1902, Evanston, Illinois – April 18, 1984, Los Angeles) was an American screenwriter and producer of films who was active in Hollywood from the 1930s to the 1960s. He was known as the favorite writer of Clark Gable and Victor Fleming.[1] In the words of one profile, he had "a flair for rousing adventure material, and at the same time he wrote some of the raciest and most sophisticated sexual comedies of that period."[2]
