Though it didn’t rival the results of last year’s Fourth of July holiday, Paramount and DreamWorks’ “War of the Worlds” turned in an impressive $77.6 million opening over the Friday-to-Monday long weekend. Playing 3,908 theaters, the Steven Spielberg-Tom Cruise alien invasion movie has a domestic total of $113.3 million in its first six days, and $102.5 million overseas in its first five days. For Independence Day openings, “Worlds” is behind only last year’s mammoth “Spider-Man 2,” which amassed $180 million for its six-day opening. The weekend’s only other new wide release was 20th Century Fox’s “Rebound,” which scored $6 million in its opening session, good for the No. 7 spot overall. In second place was Warner Bros.’ “Batman Begins,” which earned $18.7 million over the four-day span, raising its total to $154.1 million. In third was 20th Century Fox’s “Mr. and Mrs. Smith” with $12.7 million in its fourth frame, boosting its total to $146.1 million. Holding the No. 4 spot was Sony’s “Bewitched,” which made $10.8 million in its second week. Comparing the three-day portion of the weekend to its opening, the Nicole Kidman-Will Ferrell comedy dropped a steep 55%. The movie, which Sony says cost $80 million to produce but is thought to have cost significantly more, has grossed $40.3 million. Also in its sophomore session, Walt Disney’s “Herbie: Fully Loaded” placed fifth for the weekend with $10.5 million.
