It looks like Tyler Perry may have another big-screen hit on his hands. Music legend Gladys Knight and gospel artist Marvin Winans are the latest to join the cast of Perry’s latest film “I Can Do Bad All by Myself.” Taraji P. Henson and Brian White are just a couple of the actors set to appear in the film along with writer/director Perry. “I Can Do Bad All by Myself” is an adaption of one of Perry’s earlier plays.—PS
