Old Woman Thrown Out The Window
It has been so long since I have seen this movie, but I recall much of it, especially alot involving the evil Patty Duke at the end, and I recall Donna Mills entering the house and finding an old frail woman. I thought she called the woman "momma" so then this would mean this was June Lockhart, but it was an incredibly unlikely June Lockhart then.
I thought later it did seem more like June Allyson. I see June Allyson was in the cast as Olga.
Now it could have been Olga that Donna Mills said, surprised to see that Olga, whoever she was, was still alive. I do recall that.
Duke then enters in evil mode and when we see Tony Franciosa and Roz Kelly drive up outside, or after they drove up, I don't recall, but all we saw of the hysterically scared old woman with Donna Mills was that she was thrown out the window.
Was this June Lockhart of June Allyson?
I've always thought that if it was Lockhart it was very different from how I have ever seen her before. I could believe it was Allyson.
