This segment of "Playhouse 90" was made in London, using British studios and an almost all-British cast. It also marked the television directing debut of film director Terence Young, who would later make the first two James Bond films.
This episode is known as one of the most censored moments on TV. Being sponsored by The American Gas Co. they wanted all references to gas chambers removed from this drama about accountability for the Holocaust. Claude Rains conspired with fellow cast members to defy the idiotic censorship and say 'gas chamber' as originally written in the script.
