Westchester County issued the following announcement on Nov. 6.
Westchester County Government is advising that “City on a Hill” – a Showtime series set in 1990s Boston – is planning to film scenes in White Plains on November 9. The production team has requested that because our flags may be visible in their shots, the Massachusetts State and Boston City flag be flown on the westerly Michaelian Office Building flagpole, at full-staff, and to fly the United States and POW/MIA flags on the easterly pole at full-staff as well.
Following the production, all normal New York State and Westchester County flags will be returned and they will be placed at half-staff to honor the victims of COVID-19.
