Ozzy Osbourne’s final months filmed for a documentary about his move back to the UK after 20 years in the USA

Ozzy Osbourne’s final months were filmed for a documentary.

The 76-year-old Black Sabbath rocker passed away earlier this week following a long battle with Parkinson’s disease and Jack revealed his parents, Ozzy and Sharon Osbourne, had been filming a docuseries Home To Roost about their move back to Buckinghamshire in the UK after 20 years in the USA.

Jack also told the Daily Mail’s Weekend magazine that his father had finished an autobiography called Last Rites, which is due out later this year.

Jack, 39, did the interview before his father passed away and during the chat, he spoke about his work as a co-producer on an upcoming biopic about Ozzy.

He said: “Right now it’ll take place over the Sabbath era and early 1980s. We’re definitely going for a more adult rating for the film.

“This is by no means going to be a fluff piece. Right now we’re going through a rewrite with Craig Borten, who wrote [Matthew McConaughey-starring] Dallas Buyers Club.”
