There is a book on Eddie Mannix; it's called The Fixers: Eddie Mannix, Howard Strickling and the MGM Publicity Machine. It includes quite a lot of conjecture and speculation, so I tried to only include in the episode information that could be found in at least one other source. In attempting to confirm details, I came upon archival articles which complicate matters by mixing apparent truth with clear inaccuracies or spin, such as this one about Mary Nolan's lawsuit against Mannix in which he is referred to as a "Hollywood director."
