Following the teleplay's broadcast, the stage rights to the teleplay were sought by the
Dramatic Publishing Company, which was run by the Sergel family. Dramatic Publishing specialized in adapting works from other media to the stage and had previously licensed and adapted three of Rose's earlier teleplays, with the adaptations done by Kristen Sergel. Rose saw no market for a stage adaptation, and, needing money, sold the rights. Following the release of the
1957 film adaptation of the teleplay, also penned by Rose, the rights were commercially licensed, with Rose retaining the American and British theatrical rights himself. While it was several years until
Rose's version of the play debuted, Sergel's version continued to be performed by amateurs. It is still frequently performed, especially by amateurs, and for a long time was the only version licensed for performance in the United States. The existence of two distinct versions of the play, Rose's and Sergel's, has created frequent confusion between them. For Rose, however, the characters were inherently male and changing their gender would undermine his "twelve men in a box" premise and its dramatic tension. ==Plot==
