Jack Osbourne recently spoke with BBC Radio 1’s Newsbeat about his father’s documentary, ‘God Bless Ozzy Osbourne,’ which premiered at the Tribeca Film Festival in New York City April 24. Jack, who co-produced the film, said his father has “changed so much, and has become a new man who I respect.”

Jack added he wanted to highlight his dad’s newfound sobriety in the documentary: “That was the inspiration for the film. He's been sober and clean for five years.”

Jack’s main motivation for doing the documentary was to change the public’s perception of his father. In general, he was fed up with the way the media was portraying Ozzy as a “bumbling, messed up character.”

Ozzy, 62, has been sober for five years.

"I just told him, 'You claim you're this great guy, which you're not. We, as kids, have never had to go without or want for anything — well, I need a dad,' and I think that's what rang a bell with him,” Jack said.

"Just because you have a house and all the things you want physically, you still need that emotional background of a father and that's not class-specific. It doesn't mean just because you have money that's automatically what's going to happen. I think it's something a lot of people can relate to."

‘God Bless Ozzy Osbourne’ is the first film from Jack's production company, Jacko Productions. Mike Fleiss and Mike Piscitelli directed the flick. The movie includes interviews with Ozzy's family members, friends and colleagues, including Paul McCartney, Tommy Lee and members of Black Sabbath.
