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.

Some of the video used in the opening theme song specifically the exterior shot of the building was taken by John Krasinski and his friends in their Jeep. John had just gotten the part and was coming out for shooting.
