The Alan Turing portrayed in the Imitation Game was allegedly way less socially adept than the real guy. Good movie, though. I was a little disappointed in the marketing for that movie as very historically accurate, when they made a lot of choices that deviated from the historical record.
If you don’t generally like Sherlock Holmes, you definitely should not check out the BBC series with Jeremy Brett as Holmes. His portrayal, despite some fine work by other actors as Holmes in other films and series, is still considered the best.
