We’ve got a couple of casting stories to share with you this evening. First up, Clark Duke (Kick-Ass) and SAG President (and frequent 30 Rock guest) Ken Howard are the latest to join the comedy A.C.O.D. The title stands for “Adult Children of Divorce”, and the plot centers on a guy (Adam Scott) who has been caught in his parents’ ugly divorce of the past twenty years, and matters become even worse when his brother gets engaged.  Then the details of the feud are revealed in a definitive new book on children of divorce.The already stellar ensemble cast includes Scott, Amy Poehler, Mary Elizabeth Winstead, Jane Lynch, Jessica Alba, Catherine O’Hara and Richard Jenkins. Variety reports that Howard will play Scott’s amicable stepfather and Duke will play Scott’s younger brother whose engagement forces the parents to meet once again. Duke is incredibly funny and Howard brings down the house on 30 Rock, so the two are very much welcome additions to an incredibly exciting project.
