Carole Lombard (uncredited) plays one of Gloria's four friends, who are all in at least three key scenes: one in which they are eavesdropping while Tom proposes marriage, another while Gloria is getting dressed for her wedding and finally as bridesmaids at the wedding. Lombard is standing directly between and behind Tom and Gloria. Clark Gable (also uncredited) can be recognized as one of a group of men standing in front of a bar in a briefly glimpsed medium shot. It would be interesting to know if they became acquainted during the making of this film. Gary Cooper also appears in a small part - actually two small parts, as both a flood victim and a survivor.
Pioneer screen actress Florence Lawrence is said to have an uncredited bit part in this film. The only visible role of any consequence in which she might be identified is that of a customer in Mandel's Emporium who is trying on a corset, but whether or not this is her cannot be confirmed.
