Can a Hillary Clinton biopic romance US voters?

One of the top film scripts doing the rounds is a biopic about the early life of one Hillary Rodham - and her love for a certain Bill Clinton.

A talented female lawyer negotiates a man's world, brings to justice the most corrupt politician in the land, and romances the future president of the US for good measure. No, it's not Legally Blonde 3, or a feature-length Damages, it's the true story of Hillary Rodham Clinton - coming to you in time to swing the 2016 presidential election and put Rush Limbaugh into permanent therapy.

At least that's the theory. The prospect of a Hillary Clinton biopic has moved a step closer to reality with the publication of Hollywood's annual Black List - a compilation of the top unfilmed movie scripts in circulation.

This year's No. 4 is Rodham, written by Young Il Kim. "During the height of the Watergate scandal, rising star Hillary Rodham is the youngest lawyer chosen for the House judiciary committee to impeach Nixon," the synopsis goes, "but she soon finds herself forced to choose between a destined path to the White House and her unresolved feelings for Bill Clinton, her former boyfriend." It ticks all the boxes, doesn't it? Courtroom drama, political history, saxophone-backed love scenes. All it needs is a snappier title. I suggest All the President's Woman.

But Rodham also puts down an early marker for 2016's liberal Hollywood election-clincher. Despite the fact they have never made any measurable difference, pro-Democrat movies are now a regular fixture of the US election cycle. We had Michael Moore's Fahrenheit 9/11 in 2004, Oliver Stone's Bush biopic W in 2008, and Kathryn Bigelow's Bin Laden film, Zero Dark Thirty, was accused of being pro-Obama propaganda.

But more important than Rodham's political leanings is the question of who could play the 27-year-old Hillary. Reese Witherspoon? Lindsay Lohan? Meryl Streep? Chelsea Clinton? Let's not forget that Ms Rodham circa 1974 looked nothing like the modern, made-over Mrs Clinton. Perhaps Rodham will turn out to be an apolitical ugly-duckling romcom in which the dashing young Bill removes her giant spectacles and Alice band and gasps: "I've had a lot of girls, Hills, but you're my First Lady." It's box-office dynamite.
