Joan Crawford is the uncredited non-nude body double for Norma Shearer. Norma plays two roles in the film. Whenever both characters are in the same scene, Crawford plays the role that has her backside to the camera.
A dream sequence, which no longer survives, running 42 feet in Reel #4, was filmed in 2-color Technicolor.
Contrary to popular belief, more than Joan Crawford's backside can be seen in this film. When Maddy and Florence are sitting in the back of the car, that's a split-screen or double exposure of Norma Shearer - until the one shot when they hug. Looking closely at their profiles, a difference in their noses can be seen, and the one on the right is Crawford as Molly. Also, that one shot is framed a little wider than the preceding ones where Shearer plays both characters. Previously, there also had been two brief long shots of Crawford as Molly when she first arrives at David's workshop, where Florence, sitting closer to the camera, already was visiting.
Film debut of Joan Crawford, as Norma Shearer's body double. Shearer and Crawford later would be rivals, Crawford being jealous of the fact that Shearer was married to MGM production chief Irving Thalberg and, as such, got most of the roles that she Crawford wanted. The two stars later would come head-to-head (both as leading characters) in The Women (1939).
