Richard Basehart became synonymous with a high-tech submarine. Irwin Allen, who crafted entertainment right in line with the boomers' tastes, gave us "Voyage to the Bottom of the Sea." It was a sci-fi series that grew out of a 1961 big-screen release of the same name. Allen was the creative mind behind both.
Hedison was one of those stable, clean-cut Aryan men who could play a reliable leadership figure. I'm prompted to use the word "Aryan" because of a book I once read that described TV sitcoms of the 1950s as "benevolent Aryan melodramas."
Season #2 included "The Sky's on Fire" which was a redux of the storyline from the 1961 big-screen release which starred Walter Pidgeon as the admiral.
Big-screen "Voyage" had "Floyd the Barber!"

But a Vienna-based scientist says no, arguing the fire will burn itself out and the missile has risks. There's your conflict.
