When Iscah places Millie on top of a stump of a young cypress tree that had been cut down, there is a webbed foot that appears out of the water beside an alligator's head. The accurate three-fingered claw (The minimal alligator thumb cannot be seen.) appears to be connected to the alligator beside it. Though, due to the mobility of an alligator and their very short legs, it could not be of the alligator in the water. Based upon the movement of the alligators in the various scenes, real and fake alligators are used. The fake gators are in scenes with the actress and actor. At that time, or now, it is not hard to get alligator head and hide in the area of the Jacksonville, Florida, movie studios, near where this film was shot.
In the scene where Iscah places Millie on top of a stump in the swamp, a human hand appears out of the water beside an apparent alligator head. It's not clear if this is supposed to be a body part from a corpse or if it's a stuntman manipulating a fake alligator. If the latter, this would suggest an error.
The storm at sea on the yacht was filmed at San Francisco's Pier 41 with a large crowd watching, according to an article in the 6 October 1923 edition of Camera magazine.
James Kirkwood was originally cast in the role of John Woolfolk, but he was injured well into the production and could not finish the film. Director King Vidor replaced him with Frank Mayo and re-shot all of Kirkwood's close-ups and medium shots, but left in his long shots.
The sailing yacht in this film is the schooner "Yankee", built by the William Frank Stone Boatyard in San Francisco, California in 1906. A gasoline engine was added in 1923. The yacht also appears in Days of Wine and Roses (1962). In 1980 and 1999 she was extensively repaired and refitted. As of 2015 she was still sailing and entering races around the San Francisco area.
