I'm Ozzy, not Colin, says Jack Black

Shallow Hal star Jack Black believes without a doubt that Colin Farrell is the wrong choice to play Ozzy Osbourne.

In fact when he heard Farrell was being touted to play the mad metal musician in an upcoming film, Black told Sharon Osbourne on “The Sharon Osbourne Show” to think again.

He told Mrs Osbourne, "Colin Farrell? I'm saying bad call. If any one's Ozzy, I'm Ozzy. Colin Farrell, he's a good-looking dude, all right. He's kind of studly, whatever. He doesn't know the rock, though.

"I'm sorry to put you on the spot. I'm just saying before you cast him let's have a head-to-head rock-off or something."
