The Office

John Krasinski was forced to cut his hair for his role in "Leatherheads", so he was forced to wear a wig for the latter half of season 3.

Steve Carell only watched a few minutes of the British version before permanently stopping such viewing because he did not want to copy Ricky Gervais' performance as the office manager. John Krasinski, on the other hand, was an avid viewer of the original.

The computers on the Dunder-Mifflin office set are wired for the internet. Cast members have admitted that when they're in the background of scenes they are often checking email and surfing the net.
