"The character of Dr. Morelle," Mr Dudley has remarked, "was finally evolved from my memories of the silent film star Erich von Stroheim - who incidentally nearly played the part years later in a film version - and whom Hollywood used to bill as 'The Man You Love to Hate.' In order to point up the self-opinionated biting sarcasm of Dr Morelle, I gave him as a foil a pretty feather brained secretary, Miss Frayle. And so, Dr Morelle was let loose on millions of unsuspecting listeners, the first fictional character, I think, whom people hated so much they simply had to tune in and listen to him."
