"Married Bachelor" from 1941 is a light comedy, nothing special, and typical of the era. It sports an attractive, charming cast: Robert Young, Ruth Hussey, Felix Bressart, and Lee Bowman.
Young is Randolph Haven, who won't take a decent job and as a result drives his wife Norma (Hussey) nuts. They're crazy about one another, but Norma is tired of his schemes and wants him to get a 9 to 5 job.
Randolph, always looking for easy money, starts working with a bookie. But a dark horse comes in and they owe $17,000 to someone who, if he doesn't get the money, will have them measured for cement suits.
While going to people who owe the bookie money, Randolph meets a professor (Bressart) who has written, but never published, dozens of books. Randolph takes one, "The Psychology of Marriage," supposedly written by the bachelor professor. It's published, a big hit, and Randolph has to pretend he's not married.
Well, the whole thing gets mixed up. Norma feels as if she's fallen through the cracks, and when the publisher (Lee Bowman) acts interested, for spite, she flirts with him. All very platonic, of course. He doesn't know she's married to Randolph.
Ruth Hussey and Robert Young worked together several times, the last time on an episode of Marcus Welby in 1971. They made a wonderful couple. They were not first tier MGM stars, but they did good work there. The rest of the cast- Bowman, Sheldon Leonard, and especially Felix Bressart, provide solid support.
I'll take issue with one thing posted here. One of the comments was that the poster didn't know how anyone could choose Robert Young over Lee Bowman. Uh, this wasn't a reality show called Wives Who Cheat. When a woman is in love with and committed to her husband, there is no choosing; she doesn't drop her husband because someone else might be better looking. I grew up in the '50s and have a soft spot for Robert Young anyway.
