The Office could have looked much different if one NBC sitcom hadn't been canceled just a year earlier. One of the greatest comedy series of all time, The Office not only ported an acclaimed series from England to an American audience, but it surpassed the original in both critical and audience response, length, and influence. The series kicked off the mockumentary comedy boom, and several actors in the series went on to have huge careers, including John Krasinski, Ed Helms, Mindy Kaling, Ellie Kemper, and Zach Woods.
