1. Well, some of our actors got more into it than others, but I think most everyone had fun with it. We tried to give just about everyone, some stuff that they could really chew on as actors. Ed Asner and John Rhys-Davies seemed to particularly enjoy the history and myth and Shakespeare we slipped in. Keith was very protective of Goliath's character. Keith and Salli both knew where Goliath and Elisa were ultimately headed. You'd have to ask them if they were as enthralled as we all were.
2. I'm sure actors liked some scripts better than others. Sometimes they'd complain because they didn't have much to do. Other times they'd complain for the exact opposite reason. (Sort of like life.) I do remember that Nichelle Nichols really seemed to enjoy "Mark of the Panther". We saved her narration of the fable until the very end of the recording, so that we could let the rest of the actors go. She was just wonderful. I recall that Brynne Chandler Reaves and Lydia C. Marano (story editor and writer of that episode respectively) asked Nichelle to autograph their copies of the recording script. She complied, but then asked them to autograph her copy.
I thought that was pretty classy.
3. In the very first episode, Elisa has a line that's something like "You want to wind up street pizza." Try saying "Street Pizza" even one time fast. It's not that easy, and Salli kept stumbling over it. From that point on, anytime anyone stumbled over a line, somebody else, usually Salli, would bring up Street Pizza.
