That Forsyte Woman (released in the United Kingdom as The Forsyte Saga) is a 1949 American romantic drama film directed by Compton Bennett and starring Greer Garson, Errol Flynn, Walter Pidgeon, Robert Young and Janet Leigh.

Irene falls in love with unconventional architect Philip Bosinney, who is engaged to Soames' niece June.

Metro-Goldwyn-Mayer bought the film rights to The Forsyte Saga in 1937 after much negotiating over a long period of time.

[3] Initial plans were to make an all-star film in the vein of Dinner at Eight or Grand Hotel, with Norma Shearer, Joan Crawford and Franchot Tone mentioned as possible stars.

[5] James Hilton wrote a screenplay in 1938 and in 1939, and it was reported the film would be made as a vehicle for Myrna Loy.

[11][12] Compton Bennett signed to direct, and producing duties were taken over by Leon Gordon, who said the film would mostly concentrate on the story of A Man of Property (written between 1903 and 1906).

The writers included James Hilton, Richard Llewellyn, Robert Nathan, Ivan Tors, Robert Lord, Lawrence Weingarten, John Balderston, Arthur Wimperis, Ann Cunningham, Franclien McConnell, John Collier, Jan Lustig [de] and J.B. Williams.

[18] Robert Young later claimed he developed his English accent from listening to records of Maurice Evans and Laurence Olivier.

"[24] The Los Angeles Times wrote the casting of Errol Flynn as Soames "is about the only neat trick with which the filmmakers have succeeded in enlivening a photographed novel and one that is virtually without other surprises.

"[25] Bosley Crowther panned the film in his November 11,1949 review for The New York Times, beginning with what he saw as the betrayal of Irene, “One of the most intriguing characters in the English fiction of our times….And, to be quite blunt about it, Miss Garson and M-G-M have done just about as cruelly by her as anyone could possibly do.

…the script is a lot of lifeless rhetoric and the direction by Compton Bennett is absurd….”[26] That Forsyte Woman ranked ninth among popular film at the British box office in 1949.
