Olivia de Havilland's role of her life

A man is murdered, and a woman called Ruth Collins is seen at the scene of the crime.The case gets tricky, when is found out that Ruth has a twin sister, Terry.They both have to then go see a psychiatrist, Dr.Scott Elliott.The doc falls for the normal sister, but which is which? The other one of them is capable of committing a cold blooded murder, but which one? Robert Siodmak's Film-Noir The Dark Mirror (1946) takes some Freudian turns as it goes on.Olivia de Havilland shines in a dual role.She's terrific as the psychotic sister as well as the normal one.Lew Ayres is great as the Shrink.Character actor Thomas Mitchell does very fine job as Lt.Stevenson.This movie was very fascinating to watch.It gave some challenge finding out which one did it.60 years has done no harm to this film.
