Diane on AllMovie

Lana Turner stars as Diane in this opulent costume drama. Set in 16th century France, the film finds the gorgeous Diane de Pottiers rising to a position of absolute power through her manipulation of the men in her life. Those men include King Francis I (Pedro Armendariz), Prince Henri (Roger Moore) and Diane's husband, the Count de Breze (Torin Thatcher). Diane's principal foe is the scheming Catherine de Medici (Marisa Pavan), who for the first time in her life has met her match in Our Heroine. Christopher Isherwood's screenplay is literate to a fault, though the film could have used a few more action highlights. The tepid box-office receipts of Diane hastened the end of Lana Turner's long association with MGM.
