User Reviews

the best Granada feature, and a great Sherlock Holmes film
28 July 2000 | by (USA) – See all my reviews

This is a gorgeous production, expertly filmed, beautifully directed and scripted. The cast is also spot on and the pacing rarely flags.

The boat chase on the Thames is a marvel. This was the first 'chase scene' in detective fiction and it seems as fresh here as it was 100 years ago.

My one change would have been to put back the original beginning and end to the story, but the Granada production left Watson a bachelor and so there is no mention of his marriage. They had also used the 'cocaine' opening in another show and so did not repeat it here.

Jeremy Brett and Edward Hardwicke give outstanding performances and the rest of the cast is also excellent.
