She’s got a great and powerful voice… And now Mariah Carey is lending it to a great and powerful movie.

The 42-year-old part-Venezuelan singer has recorded the theme song for Disney‘s new fantasy movie Oz: The Great and Powerful, starring James Franco, Mila Kunis and Rachel Weisz.

Entitled “Almost Home,” Carey co-produced the track with Stargate and co-wrote the inspirational song with Simone Porter, Justin Gray, Lindsey Ray, Tor Erik Hermansen and Mikkel Eriksen.
“’Almost Home’ has a message that works beautifully with the film,” says the American Idol judge. “It’s a feel-good record, evoking the feeling of reaching your home and being with people that you love.”

The song will be fully released on iTunes this Tuesday February 19, with a music video directed by fashion photographer David LaChapelle to follow later on.

Oz: The Great and Powerful, directed by Sam Raimi, will open in theaters on March 8.
