The Batman movie "The Dark Knight Rises" made $64.1 million in the U.S. and Canadian box office during its second weekend, surpassing other films despite a slow market due to the Olympics and the Colorado shooting. The final installment in director 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. When combined with its domestic earnings of $289 million, the film has grossed $537 million worldwide. Despite a 60 percent drop in U.S. and Canadian ticket sales from its opening weekend, the film has still outperformed its predecessor "The Dark Knight" and other recent superhero movies. In comparison, "The Dark Knight" experienced a 53 percent decline during its second weekend in 2008, earning $75 million domestically. This year, the summer blockbuster "The Avengers" experienced a 50 percent drop in sales the weekend after its May opening, while "The Amazing Spider-Man" saw a 44 percent decline after its June release. Despite being one of the highest-grossing movies of the year, "Dark Knight Rises" did not meet pre-release sales forecasts due to the overshadowing of its opening by the tragic shooting in Aurora, Colorado. By Sunday, "Dark Knight Rises" sales in North America were behind its predecessor "Dark Knight," which earned $313.8 million domestically in its first two weekends. The impact of the Olympics and the shooting on box office sales was significant, with industry experts noting that moviegoers may have been hesitant to attend screenings following the massacre, as well as the start of the London Olympics on Friday. Paul Dergarabedian, president of Hollywood.com Box Office, described it as a "double dose" of challenges for the film industry. The Olympics has been receiving a lot of attention in the media recently, potentially causing many people to stay home on Friday night. Additionally, the Aurora shooting has also been a significant event. Lacklustre reviews for new movies this weekend likely contributed to low theatre attendance, but it is expected that next weekend will see an increase in moviegoers. The upcoming release of films like "Total Recall" and "Diary of a Wimpy Kid: Dog Days" are anticipated to attract audiences. Domestic ticket sales for the weekend were reported to be 25 percent lower than the same weekend last year, according to Hollywood.com Box Office. The second spot at the box office this weekend was held by the animated children's movie "Ice Age: Continental Drift," which earned $13.3 million. It outperformed the comedy "The Watch" and the dance movie "Step Up Revolution," both of which also debuted in theaters this weekend. "The Watch" came in third place, making $13 million at domestic theaters. The film features Ben Stiller, Vince Vaughn, and Jonah Hill as men who form a neighborhood watch group to fight aliens. Despite largely negative reviews, with only 14 percent of critics giving it positive feedback on Rotten Tomatoes. The movie "The Watch" was also impacted by real-life events. In response to the fatal shooting of black teenager Trayvon Martin by Neighbourhood watch volunteer George Zimmerman in Florida, 20th Century Fox changed the title of the film from "Neighbourhood Watch" to distance itself from the incident. Over the weekend, the $68 million production made $13 million to $15 million. Fox's executive vice president for domestic distribution, Chris Aronson, commented on the uncertain box office climate following the shooting, stating, "We didn't really know what to expect. It's a wild-card weekend for sure." Aronson expressed optimism for a recovery in the overall market, which he believed would positively impact all films. "Step Up Revolution" came in fourth place with $11.8 million in the domestic box office. The film, which follows a group of flash-mob dancers in Miami, is the fourth installment in a series that has earned over $400 million worldwide. The distributor had anticipated an opening in the low- to mid-teens. The comedy "Ted" came in fifth place with $7.4 million. The movie "Step Up Revolution" was distributed by Lions Gate Entertainment. "The Watch" and "Ice Age" were distributed by 20th Century Fox, a subsidiary of News Corp. Sony Corp's film division was responsible for distributing "Spider-Man."
