Representatives for Murphy did not immediately respond to EWs request for comment.
Earlier this year, the producer acknowledged in aninterview with theHollywood Reporterthat he did not contact de Havilland aboutFeud.
I didnt write Olivia because I didnt want to be disrespectful and ask her, Did this happen?
What was your take on that?'
Murphy said, adding, I didnt want to intrude on Ms. de Havilland.
