An FDNY firefighter died on Thursday evening while battling a blaze on the set of an Edward Norton-directed film in Harlem, the New York Post reports. Michael R. Davidson, the 37-year-old veteran firefighter and father of four, arrived at the scene after the film crew noticed smoke coming up into the set from the basement of the building on St. Nicholas Avenue, according to a statement from Norton and producers. The statement expressed the cast and crew’s “deepest condolences.” “Our hearts ache in solidarity with his family. New York City firefighters truly are the bravest in the world,” they said. The film—directed by Norton and starring Bruce Willis, Willem Dafoe, and Alec Baldwin—is based on the Jonathan Lethem novel Motherless Brooklyn and is set to be released next year. Two firefighters in York, Pennsylvania, also were killed Thursday afternoon after a building collapsed on them.
