Not really all that "office-y," but I thought this article was interesting.  Director Sam Mendes is currently filming his next feature FARLANDERS (John K. and Maya Rudolph star as an expectant couple on a cross-country road trip to find the "perfect" place to settle down), and is doing a lot of the location shooting in our old friend Stamford, CT. 

According to the article, various locations in Stamford have so far been used as a French-Canadian diner, a home in Colorado, and an Arizona bath/ whirlpool store.  The article provides a nice "peek behind the curtain" as it were on the hows and whys certain movies choose certain locations.
