 Hammer made the film "Captain Clegg" at the same time, which  concerns the same character, Christopher Syn, created by Rusle  Thorndike. Much of the basic plot is the same. Disney had purchased  the rights to the novel "Christopher Syn", based on Syn creator  Thorndikes works. It was determined that Disney had a better hold  on the copyright name of Syn, so the characters name in Clegg was  renamed Blyss.
