Colin Farrell’s all for playing Ozzy Osbourne in the biopic Osbourne’s wife, Sharon, is prepping – and from the sounds of it, Sharon has no qualms – but he has some competition it seems. Jack Black has also put his hand up to play the legendary rocker. The actor, appearing on Sharon’s show, told the host he was the right person for the role. According to The Z Review website, Black reportedly said, "Ozzy was a hero of mine as a kid and I have to say, I’ve been tracking the Ozzy film. If anyone’s Ozzy, I’m Ozzy." We’ve a sneaking suspicion, he’s not joking. Black’s film "The School of Rock" has done again bankwise, and he seems to have a lot more pull than he use to, so you just never know. Farrell’s interest in the film seems rather fleeting, if not far from concrete anyway.
