The actor and director will sit for a deposition in February, according to new court papers obtained by the New York Post.
The "Fight Club" star was shooting the movie on St. Nicholas Avenue in New York in March, 2018, when a blaze broke out. Fireman Michael Davidson lost his life fighting the fire, and his widow and five displaced tenants sued production company Class 5, Inc., as well as the building's landlord, claiming their negligence led to the blaze.
Norton is set to testify on 20 February (20).
Video footage showed the actor looking distressed as he stood outside the building as firefighters arrived.
