Thanks. I assumed he'd also directed the 'New Beginning' one. I didn't realize it was done for television. I actually liked it a lot. Perkin's performance was very touching. Probably the more-so for me because I didn't see it until he'd passed.
No, I doubt Hitch ever mentioned the idea of sequels. They weren't really done during his heyday. Well, only B movies usually, or series pictures like
The Thin Man. And Hitch, from what I've read needed to continually do something fresh to keep his interest. But I'll amend what I said. If Robert Bloch had written a 'slam bang' almost too good to be true sequel to
Psycho, I could see Alfred doing it. The man loved having a hit.
The actress in 3, Diane Scarwid (SP?), became a big deal just before 3 was released for something else she had done. For a few years people were clamoring for her, then I don't know what happened. I didn't bother with
Bates Motel. For me, when Tony Perkins died he took Norman with him. Did you see the TV thing with Bud Cort? It wasn't bad. And I read that Perkins liked it.
