In the film, "Whatever Happened to Baby Jane", Victor Buono's character seemed to be definitely a gay man.
I first saw Whatever Happened to Baby Jane? when I was in elementary school. As young as I was, I had the impression that he was quite gay. it was also clear to me that he was in it for the money.
Decades later his performance stood out in my memory--like the first time I had seen Robert Duvall in To Kill a Mockingbird, when I was a kid.
Those kind of debut performances come along once in a lifetime.
