It's been noted that Baby Dumpling was beat up at school for TWO reasons. Number one was for his mother walking him to school. Number two was his name was Baby Dumpling. Well, it was a nickname. Anyway, Dagwood got Baby Dumpling to tell him why he got the black-eye so Dagwood suggested he use his real name.......Dagwood. Later, it was revealed during 'Blondie's Blessed Event' that his real name was Alexander.
The comic strip probably hadn't given the boy a name yet and when the artist did, the movie writers went along with his name choice.
The fourth of 28 Blondie movies, all starring Penny Singleton as Blondie Bumstead and Arthur Lake as Dagwood Bumstead that were released by Columbia Pictures from 1938 to 1950.
The house used for the Bumstead's residence in the early films in this series is located in the Studio City neighborhood of Los Angeles. Built in 1937, as of 2018 it still stands and is valued at about $1.5M. For later films in the series, it was duplicated at the Columbia (now Warner Bros.) Ranch in Burbank.
This is Robert Sterling's second appearance in a Blondie/Dagwood movie. His first was his film debut in the earlier 1939 release in Blondie Meets the Boss. In this film, he makes an appearance at 13 minutes in Mr. Dither's outer office. As the men look up together from their desks towards Dagwood, Robert Sterling is the one closest to the camera. At 37 minutes as Dagwood offers cigars to his coworkers, Robert is in shirt sleeves on the right side.
