There will be no let-up in the mayhem on the silver screen over the weekend. The Warner Bros. mobster movie Gangster Squad is expected to debut at the top of the box office with around $20-25 million, while Zero Dark Thirty, which ignited a fierce controversy over its depiction of torture, goes into wide release with a predicted gross of around $15-20 million. Quentin Tarantino's bloody Django Unchained and Tom Hooper's Les Misérables, about a failed uprising in France (in which most of the characters are killed), are expected to duel for third place. Then there's Steven Spielberg's Lincoln, which opens with bloody scenes of the Civil War and closes with the president's assassination. The recipient of the most Oscar nominations this week, it could also prove to be a principal contender at the box office this weekend.
