During its second weekend, the Batman movie "The Dark Knight Rises" grossed $64.1 million in the U.S. and Canada, surpassing other films despite a slow market affected by Olympic coverage and the Colorado shooting. The final installment in Christopher Nolan's Batman trilogy, starring Christian Bale, also earned $122.1 million internationally, bringing its total overseas earnings to $248.2 million since its release on July 20. Combined with its domestic earnings of $289 million, the film has now made $537 million globally. Despite a 60 percent drop in sales from its opening weekend, "The Dark Knight Rises" outperformed its predecessor "The Dark Knight" and other superhero films in terms of box office revenue. This year, the summer blockbusters "The Avengers" and "The Amazing Spider-Man" experienced declines of 50 percent and 44 percent, respectively, in the weekend following their May and June releases. Although "Dark Knight Rises" has been successful, its sales have been weaker than anticipated due to the tragic shooting at a midnight screening in Aurora, Colorado. The film's sales in North America are lagging behind its predecessor, "Dark Knight," which earned $313.8 million domestically in its first two weekends. Warner Bros. officials have not discussed the impact of the shooting on box office numbers, but industry experts believe that the turnout for "Dark Knight Rises" and other movies may have been affected by moviegoer reluctance following the massacre as well as the start of the London Olympics. President of Hollywood.com Box Office, Paul Dergarabedian, described it as a "double dose of things." The Olympics and the Aurora shooting have been getting a lot of attention in the media recently, possibly keeping many people at home on Friday night. Lackluster reviews for new movies this weekend may have also contributed to lower theater attendance. However, it is predicted that next weekend will see an increase in moviegoers, as more time passes since the Aurora shooting, the Olympics become routine, and exciting new films like "Total Recall" and "Diary of a Wimpy Kid: Dog Days" are released. Domestic ticket sales for the weekend were 25 percent lower compared to the same weekend last year, according to Hollywood.com Box Office. The second spot at the box office this weekend was taken by the animated children's movie "Ice Age: Continental Drift," which earned $13.3 million. It surpassed the comedy "The Watch" and the dance movie "Step Up Revolution," both of which also had their theatrical debuts this weekend. "The Watch" came in third place, bringing in $13 million at domestic theatres. The film features Ben Stiller, Vince Vaughn, and Jonah Hill as men who form a neighborhood watch group to fight aliens. Despite its star-studded cast, the movie received mostly negative reviews, with only 14 percent of critics giving it a positive rating on Rotten Tomatoes. The film "The Watch" was also impacted by real-life events. In response to the shooting of Trayvon Martin by a Neighbourhood Watch volunteer, 20th Century Fox changed the movie's title from "Neighbourhood Watch." Fox predicted the $68 million production would earn $13 million to $15 million over the weekend. Fox's executive vice president for domestic distribution, Chris Aronson, expressed uncertainty about the box office performance following the shooting, calling it a unpredictable weekend. Aronson expressed optimism for a recovery in the general market, believing it would positively impact all films. "Step Up Revolution" came in fourth place with $11.8 million in domestic earnings. The film follows a group of flash-mob dancers in Miami and is the fourth installment in a successful franchise that has made over $400 million globally. The distributor had anticipated a domestic opening in the low- to mid-teens. The comedy "Ted" finished in fifth place with $7.4 million. The movie "Step Up Revolution" was distributed by a branch of Lions Gate Entertainment. "The Watch" and "Ice Age" were distributed by 20th Century Fox, which is a subsidiary of News Corp. Sony Corp's film division was responsible for distributing "Spider-Man".
