Viola Davis, Salli Richardson and Judge Mablean Ephriam have been added to the cast of Lionsgate's "Tyler Perry's Madea Goes To Jail" says Blackfilm.

The trio join the already cast Tyler Perry, Keisha Knight Pulliam, Derek Luke and David and Tamela Mann.

The latest Perry film centers on Madea (Perry), whose penchant for trouble-making lands her behind bars. She comes to the rescue of Candy (Pulliam), a fellow inmate preyed upon by a large woman named Big Sal.

Derek Luke will play Joshua, an attorney who has a past with Candy. Viola plays a social worker. Richardson plays the Atlanta District Attorney.

Judge Mablean will reprise her role as a judge she played in the two previous Madea movies.

Filming is set to begin in mid-May in Atlanta, with a tentative early 2009 release planned.
