I'll admit that the plot to "Her Master's Voice" is a bit tough to believe. However, the dialog and acting (particularly by Edward Everett Horton) is so enjoyable that I easily was able to suspend disbelief and just love the story nevertheless.
When the story begins, Ned's wife and mother-in-law pester him to DEMAND a raise from his boss...or quit! Now, considering this was in the midst of the Great Depression, this was absurd. After all, he liked his job, lived a much better life than the average American family of the time and he had nothing to fall back on if his boss called his bluff...which he did! Now, out of a job, Ned is at his lowest...and things only get worse when his wife's rich aunt arrives to stay with them. After all, she was against the marriage and thought Ned was a loser! But in a twist, she's never met Ned and when she meets him, she thinks he's a handyman/servant and she really takes a liking to him! What's next? See the film!
Although Horton is best known today as a supporting actor, in the 1920s and 30s, he often starred in comedy shorts or B-movies like this one...and most are really enjoyable. His lovely acting and screen persona really work well here and you can't help but like him and root for him through the story. Enjoyable and a lot of fun...even if the plot does get a bit silly after he meets the aunt!
