If The Doctor were to ever be American (which I hope never happens; he is intrinsically British)
Yup, an intrinsically British series co-created by a Canadian, which had its theme music and its pilot written by Australians and whose first director was from India.
Well to be fair
he was referring to the Character and not the show and besides even the Docotr has refered to himself British sort of in The TV Movie (well more accuratly Grace does, to which he agrees).
And the second serial "The Daleks" by British writer Terry nation that also set the tone.
Besides we welcome the contributions of the Commonwealth Nations in the creation of DW.
