I saw this movie in the theater when it came out, and probably twelve hundred times on HBO after that. The plot is a typical Holmesian story: stolen documents, psychological subplots, Victorian hypocrisy. Quite silly, quite enjoyable, IIRC. I'd love to see a DVD to see how much I like it now, but I have very fond memories of it, and I can still remember the words to the song Gene Wilder and the fabulous and sexy Madeline Kahn sang. Great bits of slapstick, nothing ever too serious. It doesn't even bother me that Gene Wilder, playing the brother of Sherlock Holmes, has no trace of an English accent. Bug-eyed Marty Feldman is consistently great, and Dom Deluise is at his over-the-top best, though his part is rather small, if you'll pardon the expression.
