New releases had little impact on the UK/Ireland chart this week as the top three remained unchanged from last week.
Scooby-Doo 2 held up well as school holidays came to a close slipping just 13% week-on-week.
Columbia's 50 First Dates also held up seeing a small 14% against its opening weekend (excluding previews).
Shaun Of The Dead dropped slightly more, 29% against opening weekend (excluding previews), still a small slip that will cause little concern for distributor UIP.
Leading the new openers were Icon's The Butterfly Effect and Fox's The Girl Next Door. Icon's thriller, which stars Ashton Kutcher, landed fifth with figures including previews of $306,186 (£169,802) from 222 sites.
The Fox comedy was close behind in sixth , also including previews of $295,636 (£163,951) from 239 sites. The Girl Next Door proved strongest amongst the new openers in the Republic of Ireland.
Off the chart but seeing solid limited releases were Artificial Eye's At Five In The Afternoon and Tartan Films' The Twilight Samurai.
At Five In The Afternoon took $19,157 (£10,624) from five sites for a so-so $3,831 screen average.
Twilight Samurai, one of this year's best foreign film Oscar nominees, played slightly better. It took $29,246 (£16,219) from seven sites - a $4,178 average.
