It probably came as a surprise to some that Martin Scorsese would make a family film. And that this film would be in 3D. But Hugo proved to be a more personal and emotional project for the director than might be initially suspected-for two reasons. The first is that Scorsese was the father of a young daughter, and he thought it might be good to make a movie that, unlike most of the rest of his oeuvre, she’d be old enough to watch. From that notion came an adaptation of Brian Selznick’s 2007 illustrated children’s book The Invention of Hugo Cabret, which tells the story of an orphan boy named Hugo (Asa Butterfield) who lives in a train station in Paris in the early 1930s.
