Director Michael Corrente and producer Marisa Polvino are corralling the cast for their political biopic The Prince of Providence.

Robin Williams is in talks to join Dermot Mulroney, Adam Goldberg, Bradley Cooper, Ed Burns and Oliver Platt, who will play charismatic and corrupt Providence, R.I., Mayor Vincent "Buddy" Cianci. Williams' participation will depend on scheduling issues to be determined. Steven Soderbergh has lent his name to present the production.

According to The Hollywood Reporter, David Mamet, with a script polish by Howard Korder, adapted Michael Stanton's eponymous 2003 book about the man who dominated Providence's political machine for 21 years. The drama chronicles a roller-coaster series of ups and downs for one of America's longest-serving mayors.
