Colin Farrell's publicist has spoken out to dismiss rumors the Irish actor is preparing to play wild rocker Ozzy Osbourne in a big screen biopic.

The former Black Sabbath frontman and his music manager wife Sharon are eager to transform the rocker's colorful past into a movie, and the rock matriarch has spoken of her desire to cast Johnny Depp in the lead role.

Osbourne recently admitted he would prefer an unknown actor from his native Birmingham, England to land the part - but online reports suggested fellow reformed wildman Farrell had signed up to play the Prince of Darkness.

However, the Phone Booth hunk's spokesperson has quickly denied the speculation, telling the rumor is "not true".
