Blondie!

Penny Singleton has 59 acting credits in IMDB and 28 of them are for playing Blondie Bumstead*. This is the first of those movies. Here we are introduced to Singleton's Blondie, Arthur Lake's Dagwood, Jonathan Hale's Mr. Dithers, and Larry Simms's Baby Dumpling.

Okay, plot: Blondie and Dagwood have just finished paying off their furniture, so Blondie (without telling Dagwood) replaces it all with new furniture to the tune of $22.50/month. Meanwhile Dagwood is in trouble for having signed for a loan for Dithers' former secretary who has since absconded, making Dagwood responsible for the loan. The only way for Dagwood to get the money is to make a business sale to a notoriously hard-to-sell potential client, played by Gene Lockhart. Dagwood accidentally befriends the client over their mutual interest in fixing a hotel vacuum cleaner. Willie Best plays the porter who is responsible for the vacuum. Also, Blondie suspects Dagwood of cheating on her.

Larry Simms later plays George Bailey's oldest son in IAWL. Not the one who says "'scuse me".

*Another 12 are from 1938, not including this one. She was also the voice of Jane Jetson.
