Film Crew Sets Off Sprinklers at S.F. City Hall

SAN FRANCISCO — Sprinklers flooding City Hall could easily have been a scene from a Robin Williams movie, but this was no script.

Crews filming the Williams movie “Bicentennial Man” apparently activated a sprinkler Thursday night, flooding the second- and third-floor hallways.

Heat from the camera lights may have triggered the water’s release, or lights may have hit the sprinkler system, Fire Lt. Ed Campbell said.

Water was confined to the corridors, and no offices were damaged. The water did not rise above the ankles of cleaning crews that mopped up the minor flood.

An architect was called to assess the damage, which was limited to hallway carpeting, Campbell said.

Earlier this year, city officials reluctantly agreed to let Walt Disney Pictures rent out the supervisors’ chambers at the renovated City Hall despite concerns over damage.
