This is a good film which could have been much better if it had been longer. The sets are sumptuous, the costumes accurate. Ann-Margret is uncanny in her portrayal of Pamela Harriman.Why was there no mention of her childhood, where she was fat and unloved? Why no depiction of her close friendship with Winston Churchill Sr., playing cards with him all night to raise his spirits? Why no mention of Gianni Agnelli's rejection of her? Her service as a Rothschild mistress in Paris?Many viewers will need more background to understand who the Whitneys are, who James Roosevelt was, why he was such a close parallel to Winston Churchill Jr., what role the "blackamoor" pin played in Pamela's relationship with Leland Hayward's daughter, and so on.The first half of this film will confuse even those who know her story. Stick with it. The second half shows her happy and successful marriage to Averill Harriman about as well as can be done.
