“The Amazing Spider-Man” spun its worldwide web over the July 6-8 weekend, collecting $127.5 million from international wickets, with an additional six-day domestic take of $137 million.Sony launched Spidey a week before the U.S. in 13 markets; so far, the film has grossed nearly $338 million worldwide through July 8. “Spider-Man” scored its biggest debut so far in the U.K., where last weekend the film earned $17.4 million (about 3% higher than the local opening for “The Dark Knight”), with 63% of that coming from 3D ticket sales, including 6% from Imax. Pic earned a so-so $9.6 million in Russia, but 3D grossed a whopping 77% locally. Among the blockbuster’s holdover territories, South Korea contributed $7.9 million, down just 32%, for a cume of $25.2 million. In Japan, “Spider-Man” fell roughly 40%, to $4.5 million, for a cume of $21 million after two weekends. While the global start for “Spider-Man” is certainly solid, it’s not superhero-sized. By comparison, “The Avengers” had earned $654.8 million — nearly twice that of “Spider-Man” — during its first two weekends. Spidey will face even tougher-than-usual summer competition when “The Dark Knight Rises” launches the weekend of July 20. Fox, meanwhile, already has amassed more than $200 million for “Ice Age: Continental Drift.” The studio released its fourth installment in the mega-grossing toon franchise two weeks before the U.S., where it opened July 13. Pic’s top-grossing overseas territory so far is Mexico, with $26.7 million, followed by France, which after two weekends has contributed $24.6 million.
