The Amazon-backed AI company Showrunner is attempting to reconstruct the famously-missing 43 minutes of Orson Welles The Magnificent Ambersons as a test case for the machine's ability to edit, rewrite, and overhaul a movie after it has already been filmed. Welles' completed follow-up to Citizen Kane was lost to history after studio executives ignored his notes and burned some footage. This upcoming version of The Magnificent Ambersons isn't intended for commercial use, and Showrunner did not license the rights from Warner Bros. Discovery.
