In addition to the two-part television version of the film, a shorter version was installed to show the film, entitled “Sherlock Holmes in the 20th Century.” In this installation version, in particular, the entire plot of the story “Bruce-Partington Drawings” was deleted. A film version was released before the premiere of the full (two-part) television version of the film.
