Having been a long time fan of both Basil Rathbone and Jeremy Brett in their portrayal of the world famous detective Sherlock Holmes, I always measure anyone playing the detective against these two. Ian Richardson has one very distinctive feature on his face, his nose, which was also the part I first noticed on Rathbone and Brett. So Richardson had the nose but could he be a Holmes? My answer is yes. The Sign of Four was an enjoyable film. The characters Jonathan Small and little Tonga were also very well cast. I know the story well and this film was very close to the story. Revenge, murder and the chase were all featured as well as the Bakersteet Irregulars. So if you like Holmes, give this feature a look.
