Are there actors you wish had been guest stars? I just watched And Soon the Darkness a 1970 British thriller starring Pamela Franklin who I remembered as the student with the glasses in The Prime of Miss Jean Brodie. According to her IMDB page she guest starred in a ton of American TV shows during the 70s from Bonanza to Mannix. She was in four episodes of Fantasy Island playing different characters! Then she suddenly quit acting in 1981. Seeing her in the movie I mentioned made me think she would have made a great guest in MSW as either framed niece, murderer, or victim.
