According to the Citadel Film Series book, The Films Of Errol Flynn, MGM and Warner Brothers did a swapping of stars for the services of the other. Errol Flynn went to MGM for a picture in return for Warner Brothers getting the services of William Powell for Life With Father. I think Powell made out far better in the deal than Flynn did with an Oscar nomination for Best Actor for his film.
Not that Errol Flynn was bad in That Forsyte Woman, in fact his casting as the proper and stuffy Soames Forsyte was quite a revelation. But the movie-going public simply wouldn't buy it. Errol, not the dashing hero with sword in hand and cape over the other shoulder was not accepted. If That Forsyte Woman had been made a decade earlier and for Warner Brothers, Flynn would have been perfect to play Robert Young's role of Philip Bossiney.
Flynn is married to Greer Garson and is guardian of niece Janet Leigh. Leigh is the daughter of black sheep brother in this proper Victorian family, Walter Pidgeon. Pidgeon years ago ran away with his niece's governess after the family did not permit the recently widowed Pidgeon to marry her. Back in those days proper English families did things like that.
Anyway the rather staid marriage of Flynn and Garson gets a jolt when opportunistic Robert Young who Leigh has been keeping company with, falls for Garson and she, him. In modern times it would be a no fault divorce, but things aren't done that way in Victorian England.
If there is a weakness in casting it's that of Robert Young. I'm surprised that MGM did not use someone like Peter Lawford whom they had under contract and was British besides. Greer was British, but the rest of the cast had two Americans in Young and Leigh, a Canadian in Pidgeon and Flynn was Australian. Young was older than Errol Flynn and just doesn't come over as the young opportunistic lover.
Garson of course is the perfect English lady who usually wan't allowed dalliances by MGM, but she's fine here. Greer wrote the introduction to the Films Of Errol Flynn and she says that she found Flynn to be a perfect gentleman and anxious to prove himself a serious actor.
He did in many ways in That Forsyte Saga. He was a prisoner of his own legend at this point.
