The Harry Potter actress shared the exciting news with fans via Facebook last night, saying she was thrilled to be part of the movie spectacular.
Emma said: "It was such a big part of my growing up, it almost feels surreal that I'll get to dance to 'Be Our Guest' and sing 'Something There'. My six-year-old self is on the ceiling – heart bursting. Time to start some singing lessons. I can't wait for you to see it."
The movie will be directed by Bill Condon, who helmed The Twilight Saga: Breaking Dawn – Parts 1 and 2.
Further cast have not been released.
Disney's animated Beauty and the Beast was released back in 1991. It's based on the French fairy tale by Jeanne-Marie Le Prince de Beaumont.
The movie generated more than $400 million worldwide and was nominated for five Oscars including three separate recognitions for 'Best Original Song'.
It's not the only live-action Disney movie in the offering: a live-action version of Cinderella starring Lily James and Richard Madden will be released later this year.
