==Gainsborough Studios==
The couple were hired after the war by [[the Rank Organisation]] to run [[Gainsborough Pictures|Gainsborough Studios]]. They disapproved of the [[Gainsborough melodramas]] which had been the studio's major successes for several years, and switched production to a broader range of more "realistic" films with mixed results. Box made 36 films at Gainsborough, which was merged into the Rank Organization in 1949. It has been argued Box's overexpansion "killed" Gainsborough.<ref name="edward">{{cite magazine|magazine=Filmink|url=https://www.filmink.com.au/forgotten-british-film-moguls-ted-black/|first=Stephen|last=Vagg|date=1 December 2024|access-date=1 December 2024|title=Forgotten British Film Moguls: Ted Black}}</ref>

In 1951 Box founded his own production company [[London Independent Producers]] with [[William MacQuitty]].

Box ended his cinema career in 1958 to concentrate on working in television. He was part of a consortium that launched the ITV franchise, [[ITV Tyne Tees|Tyne Tees Television]] in 1959.

According to Sue Harper and Vincent Porter:
<blockquote>Box was a skilled entrepreneur who was able to raise regular loans from the NFFC and to encourage others' talents. According to his assistant David Deutsch, he provided, more effectively than anyone he had ever known, 'the right environment for creative people to work, welcoming, encouraging and subtly influencing'. Box’s position as an outsider—a socialist of sorts, a realist by instinct, and a feminist by default—meant that he became increasingly excluded from the meritocracy. He lacked a strong visual sense, but this was supplied by Muriel Box, whose lively inventiveness was accompanied by an uncompromising sexual radicalism, which pleased her but not the distributors or the audiences.<ref>{{cite book|title= British cinema of the 1950s : the decline of deference|last1=Harper|first1= Sue|last2=Porter|first2=Vincent|date=2003|publisher= Oxford University Press|page=162}}</ref> </blockquote>
