While the fact that Joel Coen has ventured off by himself to craft the new Apple TV+ film, “The Tragedy of Macbeth,” might be surprising to some, considering he worked the past 40-ish years alongside his brother Ethan, that doesn’t mean there’s any sort of bad blood between the two brothers. That said, Joel Coen does admit that he would have never had the chance to make ‘Macbeth’ if he continued his relationship with Ethan.
