The theme is played over the title sequence, which features scenes of Scranton, various tasks around the office, and the main cast members. Some episodes of the series use a shortened version of the theme song. Starting with the fourth season, the theme song is played over the closing credits, which previously rolled in silence. The exteriors of buildings in the title sequence are actual buildings in Scranton, Pennsylvania, and were shot by cast member John Krasinski. Ferguson described his theme as "against type; it has this vulnerability, this yearning to it that soon explodes into this overdone optimism which then gets crushed - which is pretty much what the show is about."
