Q: A while back someone wrote in and inquired about a couple of scuba shows: "Sea Hunt" and "Assignment Underwater." I believe there was a third show called "The Aquanauts." What can you tell me about it?

A: Ivan Tors, the producer behind "Sea Hunt," also brought "The Aquanauts" to TV in September 1960. According to "The Complete Directory to Prime Time Network and Cable Shows," "The Aquanauts" starred Keith Larsen and Jeremy Slate as professional salvage divers when the show began; in January 1961, Larsen departed and Ron Ely (later famous as a TV Tarzan) joined the show. That February, the title was changed to "Malibu Run" and the format revamped. Considering all those changes, you will not be surprised to learn the show did not last past this single season.

Giving credit

Q: I recently watched "The Reunion," an old episode of "Wiseguy" starring Ken Wahl. He connects with an old flame played by Cathy Moriarty, but she is not listed in the credits. Can you explain why?

A: While actors will sometimes take uncredited roles, this is not one of those cases. You may have been watching an edited version of that episode; the "Reunion" I checked has "Raging Bull" co-star Moriarty listed first among the guest stars.
