2) Joan Bennet said to Victoria upon her arrival, "Welcome to Collinwood...."
Both sound like Hollywood to me.
Regarding no re-takes: What was the famous scene that Frid messed up and fought to have it re-done?
Episode one, if you look at the slate reads TAKE 2 or TAKE 3, I'm not sure which. They must have done it again. They obviously were intent on making a good first impression. Perhaps Bennett said it in the early take.
As for reshooting, from what I remember of comments about that, they would reshoot if the set fell down. I take that to mean, if the problem destroyed the entire episode. Later, as editing became easier, I think the actors implied that there was a tad more leeway. I know one person said that Bennett and Frid could get away with an occasional expletive forcing a retake.
As for the original question, I think I recall someone, I want to say Costello saying something to the effect of we were behind almost to the point of having to do a show live but it never came to that. This was at a festival and I think he made mention of taping 2 days ahead of time and having to shoot on some weekends to regain a backlog. That festival was in the 80s and I could be totally off.
