May I join Tom in expessing my sorrow on the passing of Nicholas Courtney. I didn't even know he was ill.
For me Nick, along with Tom, Anthony Ainley and Jon Pertwee made Who truly unforgettable, and was one of the reasons I beacame a firm fan in the 1970's.
He will be missed by legions of fans the world over.
The Doctor: I tell you, Brigadier, there's nothing to worry about! The brontosarus is large and placid!
Harry Sullivan: (to the Brigadier) This the patient, sir?
The Doctor: (looking up at Harry) And stupid!
