This movie could easily have become a sad and pathetic parody of the final stages of a great actor's career. Instead it marks another pinnacle in the history of one of Hollywood's greatest players, Bette Davis. There are not enough superlatives to describe her performance. Not only does Davis carry the movie, she is the movie. Her performance transcends the material. This movie is an example of where the actor succeeds in elevating the script. The story is cleverly written and beautifully photographed in a black and white context that sets the mood for the movie. But it is Bette Davis's performance as a twin which makes this movie not only watchable but fun to watch. Like Bette Davis herself, this movie has aged well. Davis has since departed us but her legacy lives on in her many wonderful movies, including this one.
