Fall’s fast start slowed this weekend, as the weekend’s new films failed to fuel much audience enthusiasm. Walt Disney’s holdover “Flightplan” led the pack for a second week, scoring $15 million in its sophomore session and dipped a modest 39% from last week’s opening. This is the time of year when Oscar-possible films begin to emerge, but other than a strong showing by Sony Pictures Classics’ “Capote,” which brought in a robust $348,978 from 12 screens in its opening (averaging a stout $29,082 per screen), few of the prestige films seem to have yet caught traction with audiences. Behind the Jodie Foster plane thriller, the top new entry was Universal’s sci-fi title “Serenity,” which bowed at No. 2 with $10.1 million from 2,188 theaters. At No. 3 was Warner Bros.’ “Tim Burton’s Corpse Bride,” with $9.8 million, down 49%. The stop-action movie has a total of $32.9 million. It was followed at No. 4 by New Line’s wide expansion of the David Cronenberg-directed and Viggo Mortensen-starring crime drama “A History of Violence,” which finished with $8.2 million from 1,340 venues. Other new wide releases finished lower down the chart, as Sony’s treasure hunt adventure “Into the Blue” came in at No. 5, posting $7 million while unspooling at 2,789 locations.
