From Tardis Wiki, the free Doctor Who reference
Fred Rawlings had an uncredited role as a Parisian in The Massacre of St Bartholomew's Eve. (DWM 233) Some sources credit Rawlings as the policeman seen during the opening credits of The Pilot Episode, although Reg Cranfield is listed as playing the part in the production paperwork for both versions of the first Doctor Who television story.
