It looks like "Mama's Boy" will have more company.
"Scrubs" actress Sarah Chalke and "Freedomland" actor Dorian Missick have joined the cast of the Warner Independent comedy starring "Napoleon Dynamite" breakout star Jon Heder, report news sources. Diane Keaton, Jeff Daniels and "Scary Movie" star Anna Faris have already been cast.
Heder plays a slacker who's still living happily at home with his mom (Keaton) until she takes up with a self-help guru (Daniels). Then everything changes for the titular hero. Faris will be a singer-songwriter.
Tim Hamilton directs and will begin production in mid-June.
Missick last appeared in "Lucky Number Slevin" and next appears in ABC's upcoming "Six Degrees" and on the big screen in "Premium" with Zoe Saldana.
Chalke is best known for playing the quirky Dr. Elliot Reid on NBC's "Scrubs," which recently wrapped its fifth season. She next stars opposite Ryan Reynolds in Warner Independent's "Chaos Theory."
