Sherlock Holmes-- for me it is always Rathbone. He looks like the illustrations Doyle approved of. When I see an actor who is not tall, long-faced and well-nosed, it feels wrong, even if the actor is good.
Baz Lurhman Romeo and Juliet, 1996..all time favourite. This film is so emotional and I really recommend watching it if you haven't already. It's a modernised version of the classic Romeo + Juliet storyline.
