SCRANTON, PA—After nearly six years on the air, NBC's hit show The Office ended abruptly Thursday when documentary filmmaker Ian Sheffield announced that he and his crew had all the footage of the Dunder Mifflin Paper Company's Scranton branch required for their project. "In retrospect, we really over-shot this thing by an enormous margin," said Sheffield, adding that he likely had more than enough good material after filming a British workplace from 2001 to 2003. "We would have finished much earlier if one employee or another didn't insist on being interviewed every three minutes. And I have no idea why we were invited to Jim and Pam's wedding. All of that stuff is totally unusable." Sheffield said that the footage will be drastically cut down and used primarily as B-roll for the planned 90-minute educational film about paper manufacture and production.
