William Harnell was my first Doctor, but my favourite was probably Tom Baker. Those wonderful vowels !
On a related subject....Doctor Who back in the 60's was really scary, at least it was to me as I was barely 10 when it started. My younger brother and I used to hide behind the sofa when the Daleks appeared. It was even worse with the Cybermen. But when I look at those old episodes now, its hard to think how anybody was scared by a load of plywood and sink plungers.
While I am on the subject, does anyone else remember "Pathways to Venus" , from about the same time ?
