Production
Filmed at Stow-on-the-Wold, Watson was portrayed as competent and intelligent as opposed to the popular idea of a bumbling character as Nigel Bruce portrayed him in an earlier series of fourteen films. He is also portrayed as a virile womanizer as the character claims to be in The Sign of the Four.

The film references A Study in Scarlet, "The Adventure of Black Peter", "The Adventure of the Musgrave Ritual" and "The Adventure of the Speckled Band". Fox would go on to play the character of Alistair Ross in another Sherlock Holmes pastiche, The Crucifer of Blood.

Reception
According to author Kingsley Amis, "the reviews were excellent." Alan Barnes calls the film "part-deconstruction, part-parody of Doyle" that "ends up resembling a long drawn-out shaggy dog story."
