This episode marked the first time, in a directing career of thirty years, that Michael Powell had worked in the United States.
The blacklisted screenwriter Paul Jarrico was still working under pseudonyms when this episode was made, and was often billed as "Peter Achilles" or "Peter A. Chilles", as he was here.
Episode writer Arnold Manoff - still being forced to write under a pseudonym at the time - died at age 50 only eight days before the episode was first aired in February of 1964. Manoff was reportedly greatly harmed by the experience of being blacklisted and it may also have led to the break-up of his marriage to actress Lee Grant, who was also blacklisted.
This is another of the several episodes of this series to be written by a writer who had been blacklisted because of their left-wing views in the decade following the Second World War. Arnold Manoff contributed this episode under the pseudonym "Joel Carpenter", which he also used on several other TV scripts.
