Apple.com has posted the second full trailer for Righteous Kill, which comes to theaters on September 12. Click below to watch the new trailer for this film starring Robert De Niro, Al Pacino and Curtis "50 Cent" Jackson.

Veteran New York City police detectives on the trail of a vigilante serial killer in the adrenaline fueled psychological thriller Righteous Kill, directed by Jon Avnet (Fried Green Tomatoes) and written by Russell Gewirtz (Inside Man). The cast also features hip-hop superstar Curtis "50 Cent" Jackson ("Get Rich or Die Tryin'").

After 30 years as partners in the pressure cooker environment of the NYPD, highly decorated Detectives David Fisk and Thomas Cowan should be ready for retirement, but aren't. Before they can hang up their badges, they are called in to investigate the murder of a notorious pimp, which appears to have ties to a case they solved years before.

Like the original murder, the victim is a suspected criminal whose body is found accompanied by a four line poem justifying the killing. When additional crimes take place, it becomes clear the detectives are looking for a serial killer, one who targets criminals that have fallen through the cracks of the judicial system. His mission is to do what the cops can't do on their own -- take the culprits off the streets for good. The similarities between the recent killings and their earlier case raise a nagging question: Did they put the wrong man behind bars?
