No. As I have said in the past, EVERY clue I write deals with something on screen... an actor, dialogue, ship, technology, etc.
I never put clues that deal with production things simply because people may not know about them. But they HAVE watched episodes. And I never put clues that has an actor on other movies/series... unless it's another STAR TREK one. But that is rare for me... in fact, I haven't done that yet.
