The ComingSoon.net Box Office Report has been updated with studio estimates for the weekend. Click here for the full box office estimates of the top 12 films and check back on Monday for final figures based on actual box office. The easy victor for the weekend was the action threequel Resident Evil: Exctinction (Sony/Screen Gems) which grossed an estimated $24 million in 2,800 theatres, exceeding the opening of its predecessor Resident Evil: Apocalypse three years ago in 400 fewer theaters, with an average of $8,400 per theatre. It’s likely to end up just outside the Top 5 of September openers. Lionsgate’s latest comedy Good Luck Chuck, starring Dane Cook and Jessica Alba, did better than last year’s Employee of the Month despite its R-rating, grossing an estimated $13.8 million its opening weekend, with an equally impressive average of $5,300 per theatre in second place. Amanda Bynes suffered her first box office bomb with the comedy Sydney White (Universal), which grossed an estimated $5.3 million its opening weekend, barely half the opening of her last two comedies, to wind up in sixth place.
