Ken Howard and Clark Duke join <strong><em>A.C.O.D.</em></strong>
Ken Howard and Clark Duke (Hot Tub Time Machine) have boarded Black Bear Pictures' comedy, A.C.O.D. Stu Zicherman is directing from a script he wrote with Ben Karlin.

The comedy centers a grown man who discovers that he was enlisted in a study about divorced children many years ago. When he's ushered into a present-day follow-up study, it wrecks new havoc on his family.

Adam Scott is staring in the film with Clark Duke playing his younger brother, whose sudden wedding announcement brings his bitterly divorced parents back into each other's lives. Ken Howard will play Scott's amicable stepfather, whose calm demeanor can't save him from becoming enmeshed in the family drama.

Richard Jenkins, Jane Lynch, Amy Poehler, Jessica Alba, Mary Elizabeth Winstead and Catherine O'Hara are all co-starring.
