Why Change Your Wife? (1920)

There's one time when real married life is absorbingly entertaining- It's when Cecil B. DeMille puts it in a picture.

Robert and Beth Bordon are married but share little. He runs into Sally at a cabaret and the Gordons are soon divorced. Just as he gets bored with Sally's superficiality, Beth strives to improve her looks. The original couple falls in love again at a summer resort.
