The plot for "My Son, My Son!" is very similar to one of Spencer Tracy's best and most underrated films, "Edward, My Son". Both are about self-made men who make the mistake of spoiling their sons...and ultimately pay the price when the boy grows into a self-destructive sociopath. I recommend both...though the Tracy one is the better of the two films.
Brian Ahern plays William Essex, a guy who comes from humble origins but who strives to work his way up out of the streets. Instead of following in his family's footsteps, he becomes a successful writer and his future appears grand. Along the way, he gets married and has a son who he adores and spoils. When his wife is unexpectedly killed, the one controlling influence on the boy is gone. What's next?
Unlike "Edward, My Son", this film emphasizes a weird Oedipal relationship that eventually develops...which is interesting though not as realistic. And, unlike the other film, you see the son (Hayward)....and, oddly, you never actually see the son in the Tracy film.
Overall, this film is exceptionally well acted and is well worth your time. Its message about spoiling a child is a tad muddled...but fascinating. Well worth your time....but the Tracy film is more of a must-see for old movie buffs.
