Golden Globe winner Brian Dennehy is in negotiations to join newly added cast members John Leguizamo, Academy Award nominee Dan Futterman, Trilby Glover and professional skateboarder Rob Dyrdek in Righteous Kill, the Jon Avnet production which begins filming September 4th in Connecticut and New York.

This rounds out the already stellar cast which includes Academy Award winners Al Pacino (Scent of a Woman) and Robert DeNiro (Raging Bull), 50 Cent (Get Rich or Die Tryin'), Carla Gugino (Night at the Museum), and Donnie Wahlberg (Saw II & Saw III).

The film, which Avnet (Red Corner, Fried Green Tomatoes) is helming based on a script by Russell Gewirtz (Inside Man), follows long time police detectives, played by Pacino and DeNiro, as they investigate a series of vigilante killings in New York City.

Dennehy (Showtime's Death of a Salesman, Assault on Precinct 13) takes on the role of their captain. Futterman (A Mighty Heart) and Glover (Starter Wife) both play attorneys, and Dyrdek (MTV's Rob and Big) a delinquent, who crosses paths with the detectives during their investigations.
