SO Disney has gone ahead and made a Christmas movie from “The Nutcracker.”

“The Nutcracker” is a staple of the holiday season, and Disney looks to offer their own take on the classic story with “The Nutcracker and the Four Realms.” Based on the original short story “The Nutcracker and the Mouse King” by E.T.A. Hoffman as well as “The Nutcracker Ballet” with stirring music by Tchaikovsky, Disney brings the classic into the modern era with a retelling of the fairy tale that puts a new spin on it.

“The Nutcracker and the Four Realms” is visually marvelous, inconsistently acted and rather incoherent in that fantasy-genre way. There’s not even that much dancing, to tell the truth. Little kids might end up too scared and adults may need several shots of insulin.

Screenwriter Ashleigh Powell has spun a tale of a spunky and brainy 14-year-old Clara who adores elaborate gear mechanisms and quotes Newton’s Third Law. One morose Christmas, she gets a present from her late mother, who sends her on a quest to the Land of Snowflakes, the Land of Flowers, the Land of Sweets and the Land of Hokum — sorry, that last one is the ominous Fourth Realm, which is overrun by rodents and fog and demented Cirque du Soleil performers.

Clara must unite all these divisive parallel worlds in time to return to her sad family and celebrate, well, being together. There are elements of Lara Croft, “The King and I” and “The Chronicles of Narnia” here, and it’s safe to say the whole film would fall apart if not for a brilliant performance from Mackenzie Foy (“The Twilight Saga: Breaking Dawn”) as Clara. Soft, angry, tender, pained and regal — Foy is absolutely luminous, both a tomboy and a princess. She speaks through her eyes and really digs into lines like “The real world doesn’t make sense anymore.”

The rest of the cast is uneven. Keira Knightley as the Sugar Plum Fairy seems to have modeled her character on Elizabeth Banks’ role in “The Hunger Games” but thought the other actress was underplaying it and so has brought twice as much irritating energy, including saying things in squeaky voice like “Isn’t it magnificent?” ″banish’d,” ″tres chic” and “oh, poo.”

At the other end of the spectrum is Jayden Fowora-Knight — he’s awfully wooden and just because he plays a former nutcracker is no excuse. There’s also Helen Mirren, who portrays the leader of the Fourth Realm with such a swashbuckling style that she’s missed when not on screen. Plus, poor Morgan Freeman tries to bring dignity to Clara’s eccentric godfather, but he’s had better lines in Mountain Dew commercials.

Directors Joe Johnston and Lasse Hallstrom also called on Misty Copeland, principal dancer for American Ballet Theater, to play the main doll in a ballet within the movie, which was a wise move. But other poor decisions mar the film, including dressing Eugenio Derbez and Richard E. Grant in over-the-top costumes and telling them to act as if they just snorted a case of Snickers bars. And there’s a moment late in the film when you realize that some of the best acting has been delivered ... by a digital mouse.

The real stars of this film are the hundreds and hundreds — sit through the credits and marvel at the number — of visual effects folk who have let us swoop over these snowy cities and forests on the wings of a bird, who use thousands of wriggling mice to come together to make one big Mouse King, and who make a legion of tin soldiers marching look positively frightening. And the lush orchestrations of Tchaikovsky, with sections repeated in different styles, show off this classic work well.

The movie is now being screened in Shenzhen. (SD-Agencies)
