Rock offspring Jack Osbourne has vowed to make the ultimate documentary about his father Ozzy Osbourne.
The reality TV star is using his own production company, Jacko Productions, to give fans a real insight into the legendary Black Sabbath rocker, which he promises to be the most accurate Ozzy documentary ever made.
He says, "I don't think anything's yet captured an all-round portrait of my dad.
"So we're trying to get away from the caricature and get a more rounded picture."
