Ring Around the Moon was based on the once-popular novel by Vera Hobart. The story endeavors to invite comparisons between the high-toned romantic adventures of wealthy Gloria Endicott (Erin O'Brien-Moore) and more earthy amours of low-born Kay Duncan (Ann Doran). Caught between both ladies is confused hero Ross Graham (Donald Cook). In her first major feature-film role, Ann Doran was drubbed by the critics, but she survived to become one of Hollywood's busiest character actresses (best remembered as James Dean's mother in Rebel Without a Cause).
