Robert De Niro stars as NYPD detective Thomas Cowan in the upcoming Righteous Kill. He co-stars alongside Al Pacino as a pair of detectives who hold up retiring to solve a case that might have meant a previous arrest they did was the wrong guy.
In Righteous Kill, Al Pacino and Robert De Niro partner as cops chasing down a serial killer. According to director Jon Avnet:
"They get along very well... What makes this movie special is how these actors, who are friends in real life, portray their friendship on screen."
