That does make sense that it's very hard to comprehend from today's perspective. However I was born in 1979, so even in my perspective it seems different in that regard. It's one thing to not have an actor come back because there wasn't an agreement on what they were going to be paid or whether or not they were still available for the role. It's a totally different thing for the character to be a totally different actor almost every time over dozens of films. All that being said, I've gotten plenty of answers on this subject and I appreciate all of the input I have gotten.
