Additionally, Williams has officially signed on to star in the comedy, “The Angriest Man In Brooklyn,” opposite Mila Kunis, Peter Dinklage, Melissa Leo and James Earl Jones.

The film is the story of a stand-in doctor who mistakenly tells an obnoxious patient he has 90 minutes to live.  The medic tries desperately to locate the man after her comments sends him on a contrite tour of the city to right all the wrongs in his life.
