 Although Lady Penelope and Parker ( the latter voiced by Graham ) were among the first characters developed , neither was conceived as a major role . Parker 's Cockney manner was based on a waiter at a pub in Cookham that was sometimes visited by the crew . On Gerry Anderson 's recommendation , Graham dined there regularly to study the accent . Anderson 's first choice for the role of Penelope had been Fenella Fielding , but Sylvia insisted she take the part herself . Her Penelope voice was intended to emulate Fielding and Joan Greenwood . On Penelope and Parker 's secondary role as comic relief , Gerry explained , " We British can laugh at ourselves , so therefore we had Penelope and Parker as this comedy team . And in America they love the British aristocracy too . ' "
