Naomi Watts, obviously, is the likeliest candidate to play Rielle Hunter in Aaron Sorkin‘s forthcoming John Edwards biopic, which Sorkin will direct as well as write. The film will be based on Andrew Young‘s “The Politician: An Insider’s Account of John Edwards’ Pursuit of the Presidency and the Scandal That Brought Him Down.”

(l.) Rielle Hunter, John Edwards; (r.) Aaron Sorkin.

So who will play Edwards, Young, Elizabeth Edwards, etc.? Movieline‘s Kyle Buchanan is saying Amy Ryan might be the best Rielle.

If this film is done right it will be a kind of black comedy mixed with a chilling portrait of an absolute cyborg — a hustler and a freak with appalling disassociative tendencies. Scott Rudin should produce this.

Sorkin said that Young’s book contains “a first-hand account of an extraordinary story filled with motivations, decisions and consequences that would have lit Shakespeare up. There’s much more to Andrew’s book than what has been reported and I’m grateful that he’s trusting me with it.”
