Sarah Shahi has been added to the cast of 'Hangman'.

The 36-year-old actress, who has starred in 'Fairly Legal', 'Person of Interest' and 'The Sopranos', will join Al Pacino, Karl Urban and Brittany Snow for Johnny Martin's crime thriller, in which she is set to play police Captain Lisa Watson.

The film's script, written by Michael Caissie and Charles Huttinger, is centered on a homicide detective, played by Pacino, who joins forces with a criminal profiler (Urban) to catch a serial killer whose crimes are inspired by popular children's game Hangman.

Michael Mandelsohn, of Patriot Pictures and Union Patriot Capital Management produces the film alongside Cheyennne Enterprises' Arnold Rifkin.

Martin, who helmed 'Vengeance: A Love Story' starring Nicolas Cage and Don Johnson, is directing the movie.

Meanwhile, Etchie Stroh, who worked on films 'The Promise' and 'Afterglow' is executive producer and will represent the film for international sales at the American Film Market, with Union Patriot Capital funding the project.

In a previous interview discussing the cast, Martin said: ''It's every director's dream to work with Al Pacino. Brittany Snow brings a fresh, instinctual presence to the production, while Karl Urban's strength, instinct, and versatility heighten the action and this genre. This film is amazing and will appeal to a wide audience.''

Shooting for 'Hangman' was scheduled to start on November 17 in Atlanta.
