Despite its persistent cultural relevance, recreating the ship was surprisingly difficult. “The Titanic is very poorly-documented,” Lynskey says. “There’s probably less than 100 photographs.” To reconstruct the skeleton of the ship, the team blended together every known detail about the Titanic, every known detail about other ships owned by White Star Line, and every known detail about other ships manufactured by Harland and Wolff. “You know the famous grand staircase? There actually aren’t any photographs of it,” Lynskey says. “The photographs you see in stories are of its sister ship, the Olympic.” To stitch together the sumptuous interiors, they further researched drapery designers, radiator suppliers, and other popular brands of the day.
