Mariah Carey’s biggest song is being turned into a movie

How would this even work?

A movie version of Mariah Carey's All I Want for Christmas is You has just been confirmed. It's said to be a holiday story which will be brought to life through CGI animation. Based on the song, and also a children's book, it will feature the Christmas classic and Mariah's voice. She will narrate the story which centres around her younger self who wants a dog for Christmas. The synopsis reads:

"When young Mariah (voiced by Breanna Yde) sees a darling little puppy named Princess at the pet store, she suddenly knows exactly what she wants for Christmas. But before her Christmas wish can come true, she must prove that she can pet-sit Jack, a scraggly rascal of a dog; in fact, the worst dog in the county! Naughty Jack turns Mariah and her family’s Christmas preparations upside down in hilarious ways. Will Jack dash Mariah’s hopes for her dream puppy? Or will Christmas reveal how love works in surprising and mysterious ways?"

Speaking about the movie Mariah said, "I am thrilled to be able to bring the story of the song to new generations of families." Glenn Ross, general manager and executive vice president, Universal 1440 Entertainment said:

"Like the song itself, Mariah Carey’s All I Want for Christmas is You is destined to become an enduring family holiday classic. It is packed with family fun, holiday spirit, poignant moments – and of course, Mariah Carey!”
