And I've lost count of the cute sidekicks: BBC - Doctor Who - Characters
I actually saw the original Dr. Who, William Hartnell, on stage in Ipswich in "Puss in Boots," a Christmas pantomime. He played Dr. Who, and at a crucial point in the play the Tardis appeared from nowhere,wrapped in smoke with its blue light flashing, and he stepped out of the police call box to our thunderous applause. Exactly how and why the Doctor was involved in the plot was beyond the credulity of anyone but a ten year old Dr. Who-crazed fan. Needless to say, I loved it! Pity they couldn't have gotten the Daleks into the pantomime. I can just hear the audience shouting back to them ,"Oh no you won't exterminate all humans!"
