McKellen stars as a 93-year-old Holmes who is now a recluse, slowly succumbing to senility. The film co-stars Milo Parker, Laura Linney and Hattie Morahan and is directed by Bill Condon.
There was no problem with Sherlock Holmes once we got the look right. It was the same with Gandalf. Once we got the look, once I looked in the mirror and saw, “Oh! There he is.” It was then very easy to, with imagination, say, ‘The man who looks like that talks like this. The man who talks like this walks like this.’ It’s, sort of, in the DNA.
