The film, based on a short story by Mick Jackson, follows what Cook calls, "two hideously ugly, weather-lashed spinsters" as they go about their daily routine of fishing and being hideously ugly. When they rescue a not quite drowned sailor from the sea, the story takes a decidedly darker turn. It's not just the mood of the piece that seems un-Aardman; rather than sticking with 3-D CG, Cook and his team designed the basics in CG and printed them out to apply the finer details in 2-D in order to achieve this grim aesthetic. "We'd never really done this before, so it was complete guesswork," says Cook. "We do 2-D all the time in commercials, but our well-known stuff is clay and plastercine model work. So I wanted to do something that had CG and 2-D and didn't go anywhere near plastercine." The film was made specifically for the festival circuit, notes Cook. "We do series work, and the features we're known for, but the smaller, auteur pieces weren't getting made," he says. Projects like these "are good for the studio, because it helps keep everyone here creatively buoyant."
