Alright so

American Gangster

Following the death of his employer and mentor, Bumpy Johnson, Frank Lucas establishes himself as the number one importer of heroin in the Harlem district of Manhattan. He does so by buying heroin directly from the source in South East Asia and he comes up with a unique way of importing the drugs into the United States. As a result, his product is superior to what is currently available on the street and his prices are lower. His alliance with the New York Mafia ensures his position. It is also the story of a dedicated and honest policeman, Richie Roberts, who heads up a joint narcotics task force with the Federal government. Based on a true story.

No Country For Old Men

Violence and mayhem ensue after a hunter stumbles upon some dead bodies, a stash of heroin and more than $2 million in cash near the Rio Grande.

I Am Legend

Robert Neville is a brilliant scientist, but even he could not contain the terrible virus that was unstoppable, incurable, and man-made. Somehow immune, Neville is now the last human survivor in what is left of New York City and maybe the world. For three years, Neville has faithfully sent out daily radio messages, desperate to find any other survivors who might be out there. But he is not alone. Mutant victims of the plague -- The Infected -- lurk in the shadows... watching Neville's every move... waiting for him to make a fatal mistake. Perhaps mankind's last, best hope, Neville is driven by only one remaining mission: to find a way to reverse the effects of the virus using his own immune blood. But he knows he is outnumbered... and quickly running

Thats all :P
