'The most expensive 14 minutes of my life,' says Colin Farrell of the sex tape in which he starred.

Colin Farrell is not, repeat not, playing the role of Ozzy Osbourne in a bio-pic. This week his publicist has spoken out to dismiss rumors the Irish actor is preparing to play wild rocker.

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

But Ozzy Osbourne himself recently admitted he would prefer an unknown actor from his native Birmingham, England to land the part. Online reports had erroneously suggested that Farrell had signed up to play the Prince of Darkness.
