Jack and the Cuckoo-Clock Heart is not a children’s film. It is a poetic, sad, and beautiful fable for adults and older teens. If you love The Nightmare Before Christmas , Coraline , or The City of Lost Children , you will adore this movie.
It seems there might be a slight confusion regarding the title There is no widely known film or animated feature by that exact name in major cinematic databases (IMDb, Letterboxd, Disney, Ghibli, etc.).
