Sean Callery has scored the pilot for the CBS drama Backstrom. The show based on the Swedish book series by criminologist Leif G.W. Persson is created by Hart Hanson and follows on an overweight, offensive, irascible detective as he tries, and fails, to change his self-destructive behavior. The pilot stars Rainn Wilson, Dennis Haysbert, Mamie Gummer, Kristoffer Polaha, Page Kennedy, Beatrice Rosen, Thomas Dekker and Camryn Manheim. Hanson is executive producing the project with Persson and Niclas Salomonsson. Callery has previously collaborated with Hanson on the Fox hit drama Bones and its spinoff The Finder.
