Are you ready to be terrified like never before this fall? Black Mass has Johnny Depp slipping into the role of real-life gangster James 'Whitey' Bulger, and it could be the moment that defines his career. A third trailer has arrived, which showcases the actor's immense talent. And it's clear that, as of this moment, he is the one to beat at this year's Oscars.

Black Mass arrives from Warner Bros. Pictures this September, just as the awards season starts to really heat up. Scott Cooper, known for his acclaimed dramas Crazy Heart and Out of the Furnace, returns to direct. And he has assembled an excellent supporting cast to back-up his leading man, Johnny Depp. Appearing in the movie are Joel Edgerton, Benedict Cumberbatch, Kevin Bacon, Corey Stoll, Dakota Johnson, Peter Sarsgaard, Juno Temple, Jesse Plemons and Adam Scott.

In 1970s South Boston, FBI Agent John Connolly (Joel Edgerton) persuades Irish mobster James "Whitey" Bulger (Johnny Depp) to collaborate with the FBI and eliminate a common enemy: the Italian mob. The drama tells the true story of this unholy alliance, which spiraled out of control. Whitey was allowed to evade law enforcement, consolidate power, and become one of the most ruthless and powerful gangsters in Boston history. Bulger was imprisoned with two life sentences in November of 2013. About the man, Scott Cooper had this to say.

"He could be charming. He could be ruthless. He was like a cobra-you never knew where he could strike. A lot of people on set knew Whitey intimately. They got chills at [Depp's] resemblance. Some of them couldn't even look at him. It's easy to be the mustache twirling villain but this performance couldn't be further from that. He is truly gifted."

Black Mass arrives in theaters on September 18. The screenplay is from Mark Mallouk and Jez Butterworth, produced by John Lesher, Brian Oliver, Scott Cooper, Patrick McCormick and Tyler Thompson, and executive produced by Brett Ratner, James Packer, Peter Mallouk, Ray Mallouk, Christopher Woodrow, Brett Granstaff, Gary Granstaff, Phil Hunt and Compton Ross. Take a look at what may be the scariest movie of the year, and is sure to overtake the Oscar's this winter! We even have two new posters.
