No, this is not the Brian DePalma film with Michael Caine. I could never get into that one, and believe me, I tried.
No, this is the 1946 Sherlock Holmes film with the one, the only, Basil Rathbone.
Yes, Nigel Bruce as Watson is actually NOT the best Watson, but keep in mind, he was the first one to give Watson a purpose on film. And yes, there were other Holmes film before this. Don't ask. Don't even think about it.
