 For many years, only the first half of the kinescope of the live  1954 TV version of "12 Angry Men" upon which this movie version is  based (shown in the series _"Studio One" (1948)_ (qv)) was thought  to survive, and had been in the possession of the Museum of  Television and Radio since 1976. In 2003 a complete 16mm kinescope  was discovered in the collection of Samuel Liebowitz (former defense  attorney and judge) and was also acquired by the museum.
