Awesomely, a teaser trailer has arrived for the highly anticipated crime thriller Righteous Kill, which has brought together Robert DeNiro and Al Pacino for the first time since they starred together in Heat (1995). Both men look grizzled and tired, which works quite well for the weathered old cops they're portraying. The two are veteran NYC policemen trying to hunt down a serial killer who targets recently acquitted criminals. Though it's just a teaser trailer, it's still totally exciting to see these two powerhouses onscreen together. Righteous Kill is scheduled to open September 12. To check out the teaser, read more.
