3. “THE SHELTER” WAS RECREATED—INSIDE AND OUT
The Shelter—where the battles took place—is based on the club [of the same name] in the basement of St. Andrew’s Hall in Detroit, which still exists. The film version’s interiors were shot on a soundstage—it wasn’t the real inside of a club. The outside—where Marshall walks off in the final scene—was a faux exterior created on the front of existing buildings. People drive around Detroit looking, but they’re never going to find it.
