Brad Pitt producing Marilyn Monroe biopic

London: Hollywood superstar Brad Pitt has stepped in as a producer to help director Andrew Dominik on his long delayed Marilyn Monroe biopic.

Naomi Watts was to play the iconic bombshell in Dominik`s biopic ‘Blonde’, which stalled before shooting was scheduled to begin in January 2011, reported Contactmusic.

However, Pitt, 48, is planning to give a new life to the Monroe film by producing the movie through his `Plan B` production company.

"We`re going to get this one done," Pitt said.

The actor has worked with with Dominik in gangster thriller ‘Killing Them Softly’ and ‘The Assassination of Jesse James’.
