Today part 3 and 4 of this great German documentary aired. Hope google translated it good enough to understand it ...
JOAN: He meant the viewerss did not want to see him alienating his Krystle. He did not even want to kiss me when he lost his memory. Aaron and Doug said to him, "You've lost your memory and still think you're married to Alexis." He said no.
LINDA: They wanted from the beginning that we have affairs. But we refused, because otherwise everyone sleeps with everyone - the only ideal would be destroyed.
JOHN: That I stood up for these principles was one of the reasons for our success. And they could not make me a second JR Ewing. First there were two locations. There was Bo Hopkins house and ours. That was completely wrong. Turning only one scene improved the series immensely. The authors and producers noted which roles were well received by the audience and that they then developed these roles is understandable. Of course this is at the expense of dear colleagues (smiles).
BO: I did not really think that the series would run. They offered me a lot of money. I particularly liked the fact that he came back with his wife. I liked my relationship with you (Al) and Linda. Pamela called me: they want to kill me in the show, I do not want that. I do not believe that. In which relationship do I still stand to whom? Since I did not know yet that the story was already rebuilt. I was pissed off.
AL (before meeting Joan): We pay for the makeup, the hairstyle, the car. We have lost all difficulties to mother. I remember exactly when Joan came it changed the whole show. Who do you owe your role to? - Joan: My agent, Aaron, Esther, Doug Cramer. Even the boy with the flap. Everyone said it was his idea.
BUNKY (Linda's assistant): Joan can wear a hat like no one else. Linda was quick in the mask finished - some others needed more time (Joan). The first time Linda and Joan fought when we were shooting on Fox grounds. Linda can not stand any kind of quarrel. So I took Joan's role and she played Krystle. So I said you go straight, you grab her and push her. Linda appears - I stand behind a container plant, grab my throat, play it to Linda. A camera panning and I'm in the picture. You can see how I play it to her. With the consequence that they took a double for Joan. I crept around and listened to the door. I went to Nolan. I heard Joan is wearing a hat. Put Linda on a Florentine.
JOAN (very first scene): I remember that I had to talk a lot. I was very nervous -I can barely remember. Whenever I looked around I saw you all and I knew what you were thinking: ok, show me what you can do.
I think she (Alexis) was a very sensitive woman who had to put off a lot of it. I found the background story much more interesting and I understood her vendetta against Blake. I felt great sympathy for Alexis. She was described in the scripts very angry and very bad. No matter how bad, she never killed anyone. I had given the role some humor. At first the series was outstanding. It was the cast, the scripts, and the chemistry that was right between us. Some despised Aaron for being so successful.
JOHN: We knew as soon as we saw her, that she not only would be wonderful, but she would help the show tremendously. If there was ever an absolutely perfect cast for a role, it was Joan as Alexis. What she played, she played her entire life. Her robes were always a big surprise for me. If a lady came in a simple pullover, I asked, what happened?
I think Joan still considers me gay today (...) because I never got involved with her. She simply was not my type. (...) That created a certain tension between us, which does not have to be generated artificially. Linda very often insisted on changes in her lines. First I went to the producers, then Linda went in. And then came Joan. It was an interesting parade.
LINDA: We often had 20, 30 costume changes. Joan and I wanted to do take clothes with us. Joan prefers full wardrobe closets. Go in the memory there it looks like in a costume rental. I have clothes for 3 lives. Nolan had already made my clothes for "Big Valley". On Dynasty he said: finally I can show your shoulders and give you the presence you deserve. We padded and padded until it gave the order from above: no more shoulder pads. There was a fight, we needed our shoulder pads. We were able to react to her (Joan). I wanted Joan to be good, I wanted all of us to be good. Because only if we were all good was the series good too. Did you ever experience that there was a fight between us? Of course, the newspaper people do not like that and they invent stories.
JUDY (Joan's assistant): She was good. She changed the whole text, or said it in a different way. She often wasn´t ready. I often interceded for her, was her light double. It's just that Joan always wanted to know what her popularity is and Krystle´s popularity and what she wears.
Bill Leaversage (driver): I picked up Joan in the morning. She looked awful and behaved like that. Always in a bad mood.
NOLAN: She has always tried to finish everyone, but to no avail. That's why people liked her, instead of hating her.
The light people became crazy trying to illuminate her (Joan's first scene and her hat).
MAXWELL: We were all just puppets of the Shapiros and Spelling.
