If Khan and Martin Crief had a baby, they would name him SHERLOCK.
Khan - Brilliant, obsessive, unemotional, physical, beautiful
Martin - Vain, childish, funny
Sherlock is really the perfect role for Benedict - and of course he is the perfect actor for this role - because he is able to show is amazing range and sensitivity. I have rarely seen an actor so skilled at making a character's soul visible, with just those micro-expressions and that lovely versatile voice.
