The man did everything -- theater, films, television, voices for video games.

The role was a perfect fit for an actor who had played important supporting roles for a similar length of time in Laurence Olivier's National theatre company at the Old Vic, but it also demonstrated his lightness of touch as well as his sturdiness.
His Watson was not an amiable old pudding-faced duffer in the style of Nigel Bruce in the series of films and radio series opposite Basil Rathbone in the 1940s; instead, he was much more the intelligent, likeable army doctor whom Sir Arthur Conan Doyle had first created. He painted this portrait in broader brush strokes when he and Brett appeared in a stage spin-off in 1988, The Secret of Sherlock Holmes, at Wyndham's theatre in the West End; this Watson, said one critic, was so stalwartly genuine that not even Holmes's hawk-like gaze could spot a hint of falsity in it.See the article for more on his career (and his heritage!).
