Maybe they'll make a comedy about New Hollywood films the way they did Hail Caesar.
The Movie's Mannix is an in-universe good counterpart to the real world Eddie Mannix.
Just suggesting both of them exist in this version of reality, and that this accounts for the historical issues in the film. In addition, the film's Eddie Mannix has Edward as a first name, the real world Eddie Mannix was named "Joseph Edgar Allen John Mannix."
