(CNN) -- Sam Raimi's "Oz the Great and Powerful" is full of famous faces and now it has some famous vocals to match.
Mariah Carey will lend her voice to the film, which stars James Franco, Mila Kunis, Rachel Weisz and Michelle Williams, in the form of a single titled "Almost Home," according to a statement.
"'Almost Home' has a message that works beautifully with the film," Carey said. "It's a feel-good record; it gives you the feeling of reaching your home and being with people that you love."
It's not yet known how the track will fit into the movie, whether it will play during the action or simply appear on the soundtrack.
What we do know is that Carey's label, Island Def Jam, will release "Almost Home" on February 19. Meanwhile, David LaChapelle is directing the music video, which he calls "a duet between Mariah and the movie," the press release states.
"Oz the Great and Powerful" is expected to bow on March 8.
