"Sunny Side Up," a major hit in its day, still entertains probably because of the combination of a winsome leading lady (Janet Gaynor), a game director (David Butler) and last but not least an integrated script and score, both created by DeSylva, Brown and Henderson at their creative peak as a trio.
The film opens with a much admired, ambitious crane shot that explores a crowded tenement street, peering into open windows and back out to the cobblestones. Much of the action is stagey and a bit forced, but the spirit behind it is admirable and prefigures a more elaborate and technically slicker sequence in "42nd Street" a few years later. This opening panorama of a certain section of society is echoed later when the action shifts to a garden party at a Southampton Estate.
The sweet-natured story involves a poor working girl (Gaynor) who dreams of pairing with a wealthy high society gentleman (Charles Farrell) whose picture she spots in the newspaper in relation to a charity function. Since this is a movie from the late 1920s with DeSylva, Brown and Henderson songs, her Cinderella dream comes true, making it all the more appropriate that she sing the best song in the film, "I'm a Dreamer, Aren't We All" not once, not twice, but three times, and always to stunning effect despite her weak and wavery vocal chords. She also manages to pull off a dandy vaudeville dance number in a street fair scene. Her leading man, Farrell, fares less well, though he transmits innocence and sincerity as well as a clear and melodious song delivery. Marjorie White and Frank Richardson contribute great supporting energy as pals of Gaynor.
Other outstanding songs are "If I Had a Talking Picture of You" and "Turn on the Heat," the latter a playfully erotic concept wherein Eskimo women are so sexy that they melt their icy surroundings, transforming them into steaming, and eventually flaming, tropics. It is the only big production number in the film, the others being focused on one or two performers in medium close-up.
