Jeremy Brett IS Sherlock Holmes, in a British tv series from the 80s and 90s. It is one of the most authentic historical depictions you’ll ever see, you’d think they sent a camera crew back in time to turn-of-the-century London.
Yes, I’ve seen Brett’s performances and it’s right up there with Rathbone and Cushing. How Hollywood passed over veteran thespians like Ian McClelland or Patrick Stewart for the part of Holmes and chose Downy is beyond me.
