As TheWrap reported in August, Hathaway has long been in negotiations for Universal's Hugh Jackman-starring adaptation of the Broadway hit. On Tuesday morning, the studio confirmed it -- and set a release date of Dec. 7, 2012.
Hathaway has at least a little experience with the show: She sang "On My Own" from the musical when she hosted this year's Academy Awards. And she sang it to Jackman.
William Nicholson ("Gladiator") wrote the screenplay.
Universal's vice president of production, Erik Baiers, is overseeing for the studio with Maradith Frenkel, director of development.
Deadline first reported the news.
