Though one might have expected friction between MGM's resident "nice lady" Greer Garson and Warner Bros. notorious "bad boy" Errol Flynn, the two got along splendidly during the filming of That Forsyte Woman. Based loosely on The Man of Property, book one of John Galsworthy's Forsyte Saga, the film casts Garson as Irene Forsyte, the independently-minded wife of tradition-bound Victorian "man of property" Soames Forsyte (Flynn). Rebelling against her husband's repressed nature and preoccupation with material possessions, Irene falls in love with unconventional architect Philip Bossiney (Robert Young). When he proves to be too free-spirited even for her, Irene moves on to the Forsyte clan's black sheep, Young Jolyon (Walter Pidgeon). Soames makes a belated attempt to win his wife back, but once again proves incapable of warmth, compassion or understanding. The casting-against-type of Garson and Flynn was fascinating, even when the film itself dragged (Flynn in fact was slated to play either Bossiney or Young Jolyon, but insisted upon taking the less characteristic role of Soames). That Forstye Woman was lavishly photographed in color on MGM's standing "British" sets.
