When it comes time to list the guest actors, the first card says "Guest Stars" (plural) and gives Elaine Joyce's name -- but the next card goes to "Special Guest Star Ned Beatty." However, the final card is also in guest-star format and says "Introducing Kelly Bishop as Charlene." There are several other shows which misuse singular and plural on guest-cast lists. This is the only Five-O show to use the word "Introducing."
