Only one new movie will be opening this weekend, and that one, Texas Chainsaw 3D, was not screened for critics. Although the movie is expected to perform well -- despite all of the recent condemnation of violent films -- most forecasters do not expect it to unseat The Hobbit: An Unexpected Journey at the top of the box office. In its fourth weekend, The Lord Of The Rings prequel is expected to gross $20-25 million, with Chainsaw coming in at No. 2 with $13-18 million. Django Unchained and Les MisÃ©rables will battle for third place, according to several box-office pundits, although at least one, Ray Subers of BoxOfficeMojo.com, predicts that Django will top the box office with $19.9 million, while Les Mis will drop to fourth place with $17.2 million. (He predicts Chainsaw to debut in second place and The Hobbit to slip to third.) Expanding to about 1,575 theaters this weekend, will be the Matt Damon/John Krasinski environmental drama Promised Land. Its debut in 25 theaters last week appeared unpromising, and it is expected to earn only around $5 million as it opens wide.
