In a 2015 interview, Henry Darrow had great things to say about the show and David Janssen. When asked how he got along with Janssen, he answered: "Wonderfully. He had a marvelous, dry sense of humor. We pulled jokes on each other here and there. When I was being replaced, he waited for me when he finished shooting earlier in the afternoon. We had a few goodbye drinks at the hotel bar. I never saw him again, though." (source: Classic Film and TV Café)

Harvey Frand, the executive at Warner Brothers who oversaw production, recalled in the 1989 book "Murder on the Air" that "the experience was wonderful because we had a good crew, and because of David. Who he was shaped what the series was about."
