Actress Jessica Chastain has dismissed reports she is in the running to play political heavyweight Hillary Clinton in a new biopic.

Film bosses in Hollywood are planning ahead for Rodham, the story of the former First Lady-turned-Secretary of State's formative years as a young lawyer, and a host of young Hollywood stars have already been linked to the role, including Reese Witherspoon, Amanda Seyfried, Scarlett Johansson and two-time Oscar-nominee Chastain, but the flame-haired star insists she's baffled by the reports.

During a press conference with reporters at Saturday's (01Jun13) Chime for Change concert in London, she said, "No, that's actually not true. I found out about the project online... There's a lot of stuff out there."
