Jessica Chastain loves to take on strong female roles, and her latest, Miss Sloane, is no different. In the film, she plays a powerful lobbyist who is the best in her business at making things happen in the often dirty world of Washington D.C. politics. When it comes to an issue she believes in strongly, she's ready to risk it all -- rejecting an offer to represent the gun lobby and taking a job at a firm with a firmly opposite stance. 

In this clip, she goes toe to toe with her boss (Sam Waterston) in a heated argument over principles, practices and publicity. Miss Sloane is now playing in select theaters and opening nationwide December 9.
