I think there was a movie where Sherlock Holmes was a woman. Can’t recall if it was period set or modern times. Might have been a tv movie or a pilot though.
Well, the show Elementary did this with DR Watson, I presume this is what you are remembering?
When I first saw this show I thought it was being done for the same reasons that warbler seems to think the DR who thing is. But since then I picked this show up again and really enjoy it.
Never actually seen that. What I’m thinking of is much older. There have been so many takes on Holmes, it’s hard to keep track. I forgot Tom Baker played him not long after hanging up the scarf.
