During the rescue scene with Susan Hayward on the bulldozer under a blanket being drenched with water, when she comes out from underneath the blanket her hair is perfectly dry.
Although the bulk of the story takes place in the early to mid-1920's, all of Susan Hayward's and Lola Albright's hairstyles and clothing, as well as those of the other female members of the cast, are strictly 1948.
