Scott & Steenburgen In Step

Adam Scott, Mary Steenburgen, Katherine Hahn and Andrea Savage have joined the cast of the Judd Apatow-produced comedy “Step Brothers” for Sony Pictures says The Hollywood Reporter.

Will Ferrell and John C. Reilly are starring as two immature, coddled men who become stepbrothers and best friends, much to the chagrin of their parents.

Scott is playing the younger, successful brother of Ferrell; Katherine Hahn plays Scott’s wife; Steenburgen is playing their mother; and Savage is Ferrell’s therapist.

Adam McKay is directing and shooting is due to start next month.
