Douglas Sirk
The famous German-born director, Douglas Sirk, made a fair share of the melodramas filmed in Hollywood.
His movies were generally filled with mirrors of all kinds and reflections of action, as Hitchcock did his trademarked cameo appearance in his films.
If we look at IMDb's list of trivia and goofs in Sirk films, his movies are filled with them. Sirk never seemed to care about all the mistakes in his pictures. Melodrama was his specialty, and he just wanted to get a strong emotional story across. His philosophy seemed to be: I want women and men viewers to cry.
Mostly, he succeeded.
