Actress Diane Lane is set to portray former U.S. First Lady and Secretary of State Hillary Clinton in a new Tv mini-series.

The Unfaithful star will take on the title role in the forthcoming NBC network show Hillary, while Frozen River director Courtney Hunt has been hired to pen the script, which will document Clinton's life as a "wife, mother, politician and cabinet member from 1998 to the present".

However, producers are still searching for the perfect man to play the politician's husband, former President Bill Clinton.

Nbc president Bob Greenblatt says, "President Clinton, we haven't cast yet. We literally just closed the deals (for the show) and haven't written the script. All that will be determined."

A premiere date has yet to be set for the four-hour mini series, but it's not the only Clinton project in the works - plans are afoot for a biopic titled Rodham, about the political heavyweight's formative years as a young lawyer.

A host of young Hollywood stars have already been linked to the movie role, including Reese Witherspoon, Amanda Seyfried and Scarlett Johansson, although another favourite, Jessica Chastain, recently insisted reports she is in the running for the job are not true.
