Title: Diane (1956 film)
Content:  The film was based on a fifty-page unpublished manuscript called "Diane de Poitiers" by John Erskine, who died in 1951. Film rights were bought in 1939 by producer Edwin H Knopf, story editor for Sam Goldwyn. Knopf tried to get financing for the film but was unable. In 1953 the project was reactivated. Knopf re-secured the film rights from Erskine's estate and took the project to Dore Schary, head of production at MGM, where Knopft had a deal. Schary agreed to finance. Greer Garson was originally mentioned as a possible lead. Schary also announced he hoped to get Greta Garbo to come out of retirement to play the role. It eventually went to Lana Turner. Turner said Diane was an interesting woman "one who used her charm intelligently. Actually she was a forerunner of today's modern woman; she was Europe's first outdoor girl, a health fan and an advocate of the cold bath. She wasn't afraid to use her head, but was never caught with her brains showing."
