Warner Bros. scored another hit in the UK at the weekend when A.I. Artificial Intelligence took the top chart position with $3.3m (£2.3m) from 428 sites, including previews of $424,616. With a site average of $7,819 the Steven Spielberg film had a strong opening weekend, the distributors second highest of the year so far, after Cats & Dogs' $5.4m (£3.7m) over the August 3-5 weekend.

The science fiction tale starring Haley Joel Osment and Jude Law (who were up against each other for the 1999 Best Supporting Actor Oscar for The Sixth Sense and The Talented Mr Ripley respectively), will have its real test next week as it encounters strong competition from The Score and Enigma.

Still performing well, despite losing pole position to A.I., was 20th Century Fox's Moulin Rouge which dropped off just 18% from the previous weekend to gross a three-day figure of $2.2m (£1.5m) over its third weekend on release. The musical, currently at number two in the chart, has already racked up $12.2m in just 17 days at the UK box office. The top five was filled out by The Fast And The Furious ($1.7m), A Knight's Tale ($757,020) and Scary Movie 2 ($540,545).

Another Warner Bros release, Cats & Dogs, is also holding strong in the chart at number six. With a week-on-week drop off of only 23% the canine versus feline film managed $410,067 in its eighth weekend on release bringing its total gross to a massive $31.1m, making it the fourth highest grossing film of the year so far, after Bridget Jones's Diary ($61.4m), Shrek ($41.2m) and Hannibal ($31.6m).

Other openers to make the chart were BVI's Kirsten Dunst drama Crazy/Beautiful, which scored $198,384 (£135,496) from 141 sites to claim tenth position, and Eros International's Ajnabee at 15, grossing $87,827 (£59,986) from just 17 sites - a site average of $5,166.

Also opening well, but failing to make the chart, was The Circle (Dayereh) which took a three-day total of $30,382 (£20,751) from 7 sites for distributor Artificial Eye.
