UPDATE: Deadline just added that his Django Unchained role has been scrapped completely, due to scheduling conflicts with Boardwalk Empire.

The original post below…

We already know that Michael K. Williams booked a role in an upcoming film called Snitch, which already stars Dwayne "The Rock" Johnson and Susan Sarandon.

Now we know what exactly that role will be; Williams, who's also up for a role in Django Unchained (a story we broke in an interview he did with Monique a few weeks ago), will play "a narcotics kingpin with a short temper who becomes involved with a man (Dwayne Johnson) who is turning DEA snitch to get his son a reduced prison stretch."

Shooting is scheduled to begin next month.

And regarding his potential role in Django Unchained (or, the movie that's supposed to "revolutionize" Hollywood with regards to its *race matters,* according to some; hey, wait a minute, I thought Red Tails was supposed to be the movie with that burden?)… Deadline now says that they're hearing Williams will play "muscle for ranch owner Calvin Candie (Leonardo DiCaprio)."
