Acton native and Marshfield regular Steve Carell was the surprise guest at “The Office” wrap party in Scranton, Pa., over the weekend. Carell, who played Dunder Mifflin boss Michael Scott for years before leaving the NBC show in 2011, joined his former costars, including Newton actor John Krasinski (a.k.a. Jim Halpert) for a visit to the city where ”The Office” takes place. “The Office” has employed a pack of Massachusetts-bred actors and writers over the years including Carell, Krasinski, Mindy Kaling, B.J. Novak, and Lee Eisenberg. The series finale airs on May 16. Above: Carell (center) answers a fan question along with the rest of the cast at PNC Field in Scranton.
