SAG-AFTRA is offering condolences to a New York fireman who was killed Thursday night while fighting a fire that broke out on the set of the movie Motherless Brooklyn, which stars Bruce Willis and Edward Norton, who’s directing.

“We offer our deepest sympathies to the families, friends and colleagues of New York City Firefighter Michael R. Davidson and all of the heroes who have made the greatest sacrifice. We honor your lives and are deeply grateful for your service,” SAG-AFTRA president Gabrielle Carteris and national executive director David White said in a statement. “Every day in cities across the country, firefighters put their lives on the line to keep us safe. Their bravery is unmatched and their service invaluable.

“Last night in Harlem, members of the New York Fire Department protected SAG-AFTRA members and others on a production set. We are so grateful for their efforts and are deeply saddened to learn that several of those firefighters were injured and one lost his life.”

The cause of the blaze, which broke out in a five-story building that had once been home to St. Nick’s Jazz Pub, remains under investigation, but a statement released by the film’s producers indicates that it started on a floor below where they were filming.

“Our production was towards the end of our working day and had dozens of people working on site, when our crew noticed that smoke was coming into our set and into other parts of the building from below us,” the producers’ statement said. “As soon as we noticed smoke coming up into our set, our crew immediately alerted the fire department and began alerting residents of the building even as we evacuated our cast and crew. Our hearts ache in solidarity with his family.”
