Universal Studios’ “Coraline” snagged the No. 2 spot on all three charts — the Nielsen VideoScan First Alert and Blu-ray Disc sales charts, and Home Media Magazine’s rental chart — and even though the edgy animated hit didn’t play straight to the young-male demo that swarmed all over “Watchmen,” a solid 18% of its unit sales came from Blu-ray Discs, a surprisingly strong showing that indicates the format is fast moving out of the early adopter phase and into the mainstream.Summit Home Entertainment’s “Knowing” placed third, again on all three charts, with 17% of its sales in its third week of release coming from Blu-ray.”Coraline” sold 70.7% as many copies and generated 63.7% as much rental action as “Watchmen,” a good showing given the film’s lower box office gross of $75.3 million. “Watchmen” earned $107.5 million.Elsewhere on the charts, Warner’s “Robot Chicken: Star Wars — Episode II” debuted at No. 6 on the First Alert chart for the week ending July 26. Three TV DVD season sets also finished in the top 10: 20th Century Fox’s “Prison Break: The Final Break” at No. 8, Universal Studios’ “Psych: The Complete Third Season” at No. 9, and Warner’s “Pushing Daisies: The Complete Second Season” at No. 10.Meanwhile, Universal Studios’ “Fast and Furious” came out of the gate with a vengeance July 28, selling nearly 25% of its initial retail shipment on its very first day of release.
