The same studio that brought forth Father Was a Fullback was responsible for Mother is a Freshman. Loretta Young stars as Abbigail Abbott, the widowed mother of coed Susan Abbott (Betty Lynn). In order to legally validate Susan's scholarship fund (a legacy of her late grandmother), Abigail enrolls in the university as a freshman. Here she is wooed by Professor Richard Michaels (Van Johnson)--much to Susan's dismay, since she'd set her cap for the professor herself. Rudy Vallee reprises the "stuffy middle-aged suitor" characterization he'd essayed in such previous comedies as The Palm Beach Story and Bachelor and the Bobby-Soxer. Mother is a Freshman afforded audiences the opportunity of glimpsing 20th Century-Fox's familiar "college campus" sets in full Technicolor (these standing sets were also seen in black & white in such 1949 releases as Mr. Belvedere Goes to College and It Happens Every Spring).
