In this moving 2015 animation by Alain Gagnol and Jean-Loup Felicioli (A Cat in Paris), a young cancer patient with the power to leave his body helps a cop whose legs have been broken bring down a criminal mastermind holding New York City hostage. Able to fly anywhere invisibly, but unable to touch anything, the boy acts as a spy for the cop, who’s been marginalized by the force for his reckless methods, and as a guide to the enterprising journalist also trying to save the city from the gangster. The noirish plotline is smart and engaging, but this French film is most powerful for its treatment of the young hero’s illness; in one scene he uses his supernatural ability to eavesdrop on his family as they discuss him. In French with subtitles.
