The Nightmare Before Christmas (lost original Vincent Price audio for stop-motion animated film; early 1990s)
The Nightmare Before Christmas is a 1993 stop-motion film directed by Henry Selick, produced by Tim Burton and Denise Di Novi, and written by Caroline Thompson and Michael McDowell. It was released by Walt Disney Pictures under their Touchstone Pictures banner.
The movie originally had Vincent Price as the voice of Santa Claus, but due to his health declining after his wife's death, his voice became frail and weak and his recordings were deemed unusable, leading to the role being recast, much to Selick's regret.
Price's voice work has not been publicly released and it's unknown if either Selick or Disney even still have the recordings.
