'Black Mass' Trailer: Benedict Cumberbatch's Boston Accent And 3 More Things We Learned From New Teaser [VIDEO]

When the first teaser for “Black Mass,” Scott Cooper’s (“Crazy Heart”) upcoming film starring Johnny Depp as notorious Boston gangster James “Whitey” Bulger, was released the internet exploded with hype that Depp was headed for an Oscar nomination. The full trailer for the movie, which hit the internet Thursday, revealed that the movie has a lot more going for it than just Depp’s performance.

Here are 4 things we learned about “Black Mass” from the new trailer:

1. The Cast in Incredible

The first teaser for "Black Mass" focused almost entirely on Depp in a tense scene at the dinner table. However, the full trailer for the movie highlights a stacked cast of Oscar nominees and stars including, Joel Edgerton, Benedict Cumberbatch, Rory Cochrane, Jesse Plemons, Kevin Bacon, W. Earl Brown, David Harbour, Dakota Johnson, Julianne Nicholson, Corey Stoll, Peter Sarsgaard, Adam Scott, and Juno Temple. Depp may be the highlight, but there is a lot to love in this cast.

2. Benedict Cumberbatch Has a Boston Accent

Speaking of Benedict Cumberbatch, the popular "Sherlock" actor has stuttered for "The Imitation Game" and voiced a dragon for "The Hobbit" series, but here he sports a Boston accent to portray state senator and brother of White Bulger, Billy Bulger. The legion of Benedict Cumberbatch fans will likely flip hearing the actor try his hand at the city's iconic inflection.

3. There Will Be Blood

The trailer notes Whitey Bulger's rise from street thug to Boston crime boss and, as the saying goes, you can not make an omelette without cracking a few eggs. The "Black Mass" trailer promises a lot of violence as clips show Bulger shooting a shotgun at a moving vehicle, kicking a man on the ground, and much more. Whitey and his brother Billy might both appear in the film, but this is certainly no family film.

4. A Lot of Ground is Covered

According to the trailer, Bulger's decades-long rise to power was precipitated by a dirty FBI official, played by Joel Edgerton, who allowed Bulger to act with impunity for years in exchange for favors. The movie appears to tell a long and complicated story of corruption stretching from Bulger's early crime days in the 1970's until his capture after years as a fugitive in the early 2010s.

"Black Mass" will premiere in theaters on Sept. 18. Watch the trailer below:
