King Kong was in 19th place, but will feature higher by the end of the year.

"I would expect to see Narnia in the top five and Kong in the Top 10 by year's end," said Robert Mitchell, Screen International's chief box-office analyst.
Fantasy blockbusters feature prominently in the rundown, with Steven Spielberg's War of the Worlds at five, superhero prequel Batman Begins at 11 and comic-book adaptation Fantastic Four at 15.
Animation has also proved popular with UK audiences, with animal caper Madagascar at seven, Robots at 17 and Valiant at 20.
The only wholly British film in the Top 10 is Nanny McPhee in tenth place. Starring Emma Thompson as a magical governess, the family comedy took £16.3m.
Pride and Prejudice and The Hitchhiker's Guide to the Galaxy - both Anglo-American co-productions - are at 12 and 18 respectively.
King Kong distributor UIP has had a spectacular year, with combined takings from its seven Top 20 title sure to exceed £155m by the end of 2005.
Cheer up Kong - you'll be in the Top 10 by New Year's Eve
Sony Pictures, in contrast, only has one title in the rundown: Will Smith's comedy Hitch, which charts at nine with takings of £17.3m.
Other comedies that have tickled the British public's funny bone over the last 12 months include Meet the Fockers and Wedding Crashers.
Last year's box-office champion was Shrek 2, which made £48m in 2004. Harry Potter and the Prisoner of Azkaban came second with £46m.
