Martin Scorsese's "Hugo" is a children's film for grown-ups – grown-up film buffs.

It's a charming and quite gorgeous exercise in the few corners of the medium where the Oscar-winning filmmaker has next to no experience – children's stories, comedy and 3-D. And even though it is too long, this adaptation of Brian Selznick's "The Invention of Hugo Cabret" is a stunning exercise in 3-D and a delightful celebration of Scorsese's love of movies – something he, like Hugo, developed in childhood.

Hugo (Asa Butterfield) lives in the bowels of a Paris train station in between the World Wars. He is an orphan who hides out, carrying on the job a drunken uncle left him with – servicing the huge clocks there. He slips in and out of the station, getting by on stealing food and drink, hoping not to be noticed by the station inspector, Gustav (Sacha Baron Cohen).

Hugo's a tinkerer, something he picked up from his late father (Jude Law). His favorite project is an old clockwork automaton, a wind-up man he tries to fix with parts stolen from the toy shop run by a cranky old man played by the great Ben Kingsley. When the old man catches Hugo, he seizes the boy's notebook, full of his father's drawings and fixes for the automaton. Hugo must work in the shop to win the notebook back, and even then, the mean old man may turn him in to the meaner wounded war vet Gustav, who patrols the station with a Doberman.

Isabel (Chloe Moretz) calls the old man "Pappa Georges," and even she finds Hugo dubious company, an excuse to try out her burgeoning vocabulary – "You're nothing but a … reprobate!"

Hugo must win her over (he takes her to the movies to see Harold Lloyd in "Safety Last"), elude Gustav and get that notebook – his last tie to his dead father.

Scorsese uses this vintage Paris railway station set to stage marvelous 3-D chases, on foot – his camera following Hugo up ladders, down alleys, weaving through crowds. "Hugo" is the best- looking 3-D movie since "Alice in Wonderland."

The director peoples the set with character players (Richard Griffiths, Emily Mortimer, Christopher Lee), and sets in motion subplots about the lonely Gustav, the fate of Hugo's drunken uncle (Ray Winstone of "The Departed") and clues to the automaton's and Pappa Georges' past.

Moretz, slinging an English accent, is her delightful self, and Kingsley goes from ogre to charmer in his usual winning `fashion.
