Richard Leech and June Thorburn get married. This puts paid to a feud their families have been involved in for fifty years. However, now there's a new reason for the elders to fight. Evan Thomas and Marjorie Hume, the local aristocracy, announce a cottage for the couple with the most grandchildren. That's Eddie Byrnes and Marjorie Rhodes, but Leech's family and Miss Thorburn family are neck and neck for second place, and might edge out the leading couple... especially as Miss Thorburn is expecting.
It's a bit of a nasty comedy, as the old ladies snipe at each other and try to tweak the numbers so each will win. With the film's title, it looks like the producers were trying to suggest that was an Ealing-style comedy, and there's certainly a bit of that in the intentions. Mostly, though, it's watching the old people be funny or charming as the situation calls for it, and the young couple, with some nice chemistry, be in love.
June Thorburn is a particularly winsome young woman. She had hit the big screen with a role in THE PICKWICK PAPERS three years earlier, and by the time she retired from the movies in 1963, she had appeared in almost two dozen. She was married twice, with a child from each marriage. She was killed carrying her third in a plane crash in 1967, 36 years old.
