The weekend before the Christmas holiday will see crowded marquees as three films make their debut, each of which is likely to overtake last week's winner, Mel Gibson's Apocalypto, according to analysts. However, there is no consensus on which of the three, Eragon, Charlotte's Web, or The Pursuit of Happyness will come out on top. Joining them in very limited release will be Paramount's musical, Dreamgirls, in Los Angeles, New York and San Francisco and Warner Bros.' The Good German, starring George Clooney, in New York, Los Angeles, and Toronto.
