EW's Michael Ausiello reports that the producers are shopping around for a new cast member, and they're looking to HBO stars Danny McBride (Eastbound & Down) and Rhys Darby (Flight of the Conchords).Though sources confirm that these actors are under consideration for a new role, Office showrunner Paul Lieberstein cautions against making cursory conclusions."We haven't settled exactly who will take over," says Lieberstein.Whether it be a new cast member or a seasoned veteran rising up to fill in, it's clear that The Office has some big shoes to fill.
