Mariah Carey has landed a new film project fresh off the release of “Tennessee,” a project she filmed a few years ago. Carey has been cast to appear in “Push,” a drama where the “I’m That Chick” singer will portray a Harlem, NY social worker who is working with an overweight, HIV-positive woman impregnated by her father. According to NY Daily News, Carey was cast in “Push” by filmmaker Lee Daniels’ who also worked with the singer in Tennessee. In related news, Mariah Carey is reportedly developing a musical based on her popular 1994 holiday album “Merry Christmas.” The project is set in a town outside a city where a ruthless developer wants to turn it into one big mall. “Mariah doesn’t want to let that happen,” says her producing partner and recently reassigned manager Benny Medina. “Her character uses song and love to keep the Christmas spirit alive.” Mariah says the script is still in the early stages, “Since I recorded the Christmas album, I’ve always wanted to make a movie to go with it, something that people could watch and hear and enjoy every year. I’m into it. I’m all about the holiday season.” Carey’s “Tennessee” is slated for release later this year.
