Veteran rocker Ozzy Osbourne will confront his "personal demons" thanks to his son Jack, who is producing a new documentary about the star.
The former Black Sabbath frontman became a reality TV fixture with his family's lighthearted hit MTV show The Osbournes.
But Jack, has vowed to capture his father's complexity in the feature, planned as the first release from his Jacko Productions.
He says, "MTV couldn't show the darkness and so they used all the goofy things, but that's not really who he was at the time. Dad has been sober for three years, and I've never seen him more focused, honest and straight-up. He refuses to do a book, because he's terribly dyslexic, can't write and doesn't want a ghostwriter, so I thought, why not make this his talking book?
"I want people to see John Osbourne as the guy I grew up with, the tormented, complex musician whose personal demons manifest themselves in so many crazy, unique ways. He's agreed to it but is putting up his guard, massively afraid of putting his true self out there on display for people to see."
Osbourne has filmed several of his father's concerts and is working on an interview with the rocker's first wife, Thelma Mayfair, for the project.
He will executive produce the documentary alongside his mother, rock matriarch Sharon Osbourne.
