Joseph Edgar Allen John "Eddie" Mannix (February 25, 1891 – August 30, 1963) was an American film studio executive and producer.
He is remembered for his work protecting Hollywood stars as a "fixer", a person paid to disguise details of the stars' often colorful private lives to maintain their public image.
Among his most lasting contributions to Hollywood was a ledger he maintained that lists the costs and revenues of every MGM film produced between 1924 and 1962, an important reference for film historians.
