Jessica Chastain's Movie 'Miss Sloane' Adds Meghann Fahy

Jessica Chastain walks around the set of her upcoming movie Miss Sloane on Monday (March 7) in Toronto, Canada.

The two-time Oscar-nominated actress is starring in the movie about “a ruthless and highly successful political strategist named Elizabeth Sloane who exposes the cutthroat world of D.C. lobbyists on both sides of the gun legislation debate.”

Meghann Fahy, best known for her work in Broadway’s Next to Normal and the FX mini-series Political Animals, has joined the cast of the movie. She will play “Clara, a lobbyist on Chastain‘s team who gets bamboozled by one of her bosses’ ploys,” according to Deadline.
