I realise this is a big ask, but I would love it if anyone could help.
I'm a Doctor Who nut (we prefer the term Whovian incidentally, sad I know), as well as a motorsport enthusiast, and recently something came to my attention which may well link my two obsessions.
In 1970 the BBC broadcast the Doctor Who story "Inferno" starring Jon Pertwee as the Doctor. This story has just recently been released on DVD, with a "Making Of" documentary as an extra.
The story called for a number of action sequences featuring the Doctor, at speed, in his bright yellow roadster "Bessie". In the "Making Of" Documentary it is revealed that Jon Pertwee insisted on doing these sequences himself, instead of hiring a stunt driver to do them.
Apparently Pertwee had raced cars previously, and enjoyed driving at speed. One of the production team interviewed in the documentary mentions that Pertwee had run at Brooklands, though my gut reaction is that he might just be mentioning Brooklands as it's the only racing circuit he can remember off the top of his head.
I would love it if anyone here knows, or could find any information, about Jon Pertwee's racing career, where, when and what in for example.
It does seem that Pertwee was a lover of all things automotive and insisted on bringing aspects of this to his portrayal of the Doctor. He even commissioned the building of The Whomobile for use in the show. With that in mind perhaps it's possible that he did have some sort of racing pedigree?
