EXCLUSIVE: Meghann Fahy (Next to Normal, Lost Girls) has joined EuropaCorp and FilmNation’s feature film Miss Sloane in what is a fairly substantial role. Headlined by Jessica Chastain and directed by John Madden (Shakespeare in Love), Fahy steps into the part of Clara, a lobbyist on Chastain’s team who gets bamboozled by one of her bosses’ ploys.

Miss Sloane follows the story of a ruthless and highly successful political strategist named Elizabeth Sloane (Chastain) who exposes the cutthroat world of D.C lobbyists on both sides of the gun legislation debate. As cries for legislation for more stringent background checks reaches a fever pitch in D.C., Sloane is approached to spearhead a campaign for gun manufacturers but decides against it, which pits her against the formidable power of both her lobbying firm and political opponents. Deploying her skills – and driven by a desire to win at all costs – she jeopardizes those closest to her, and puts her own career at risk — shocking everyone around her, including Clara.

Fahy, who starred for two years as Hannah O’Connor in the soap One Life To Live, is repped by The Gersh Agency and Untitled Entertainment.
