nigel bruce-- what a legend as watson.
also thoroughly enjoyed ian hart,terence rigby and james mason in the role.
An honourable mention for Andre Morell, I think.
i agree i also enjoyed tom baker as holmes and love all four episodes of hotb,but i thought rigby was a really good watson.
I have to say that Terence Rigby as Watson was a big disappointment to me too. Although Tom Baker has never rated his own performance as Holmes, I think he did a good job, although he was far too physically bulky. The production itself is similar: solid and workmanlike.
James Mason fiddling around with those peas on his dinner plate until Sherlock crushed them with his fork!
