A Movie From My Childhood

On one Sunday afternoon when I was 6 my mother took me to the movies to see this film. I remember thinking at the time how beautiful Natalie Wood was and how funny this movie was. I think I remember a part of the movie where she was on the couch of a therapist telling him how she felt neglected or something like that. Anyway, I have looked and looked for this movie over and over again since the beginning of VHS rentals and wonder why it has never been released to the video. There are a lot of her movies it seem that have not been released to video, it is curious to me. If anyone has any ideas why or knows why that is I would be interested. Its kind of a little "pebble in my shoe" sort of thing that just keeps coming up every time i am looking for an old movie to watch.
