George Romero originally wanted Betty Aberlin to appear as the lead in his classic Night of the Living Dead, but that decision was blocked by this man, Aberlin's then employer and Romero's former boss. This man has only once acted as a fictional character, and that wasn't a stretch, as he appeared as a reverend in one episode of Dr. Quinn, Medicine Woman. Identify this immortal figure whose trip to the hospital to get a tonsillectomy was filmed by Romero, which he once claimed was the scariest thing he has ever filmed.
