Mariah Carey has debuted the video for her new single "Almost Home," and if you're tired of watching her in color on American Idol, well, you're in luck.

"Almost Home" is from the new movie Oz the Great and Powerful, a prequel to the beloved 1930s film The Wizard of Oz.  And like that classic movie, it starts out in black-and-white and turns color when the main character, played by James Franco, arrives in the Land of Oz.  So in the video, Mariah's all in black-and-white as well, but surprisingly, she stays that way throughout.

The video, directed by noted fashion photographer David LaChapelle, features Mimi looking old-school glamorous, with a long black gown, big diamond earrings and long flowing hair.  As she sings in a room that's empty except for a stool, we see scenes of the Disney film flashing by, with Franco, plus co-stars Michelle Williams, Rachel Weisz and Mila Kunis, lots of special effects and even flying monkeys. 

At the end of the clip, when Mariah opens her mouth and holds a long note, there's a clever sequence that shows a montage of the movie's stars with their mouths open, as though they are singing as well.

Oz the Great and Powerful is now in theaters.
