WELLINGTON – A crate full of sushi arrives. Workers wearing wetsuit shirts or in bare feet bustle past with slim laptops. With days to go, a buzzing intensity fills the once-dilapidated warehouses where Peter Jackson's visual-effects studio is rushing to finish the opening film in “The Hobbit” trilogy. The fevered pace at the Weta Digital studio near Wellington will last nearly until the actors walk the red carpet Nov. 28 for the world premiere. But after “The Hobbit: An Unexpected Journey” hits theaters, there's more work to be done. The special-effects workforce of 150 on “The Lord of the Rings” trilogy a decade ago now numbers 1,100. Only five of Weta Digital's workers are actual employees, however, while the rest are contractors. Many accept the situation because movie work often comes irregularly but pays well. Union leaders, though, say the workers lack labor protections existing in almost any other industry. Like many colleagues, Weta Digital's director, Joe Letteri, came to New Zealand in 2001 to work on the “Rings” trilogy for two years. The work kept coming, so he bought a house in Wellington and stayed. “People come here because they know it's their chance to do something really great and to get it up on the screen,” he said in a recent interview. “And you want to do it in these next two weeks, because the two weeks after the movie's finished are useless.” Little of Weta's current work was visible. Visitors must sign confidentiality agreements, and the working areas of the facilities are off-limits. The company is secretive about any unannounced projects, beyond saying Weta will be working solidly for the next two years, when the two later “Hobbit” films are scheduled to be released. The workforce has changed from majority American to about 60 percent New Zealanders. The only skill that's needed, Letteri says, is the ability to use a computer as a tool. Beyond having creativity as a filmmaker, Jackson has proved a savvy businessman, Letteri says. “The film business in general is volatile, and visual effects has to be sitting right on the crest of that wave,” Letteri says. “We don't get asked to do something that somebody has seen before.” The government calculates that feature films contribute $560 million each year to New Zealand's economy. Like many countries, New Zealand offers incentives and rebates to film companies and will contribute about $100 million toward the $500 million production costs of “The Hobbit” trilogy. Almost every big budget film goes through Jackson's companies. “New Zealand has a good reputation for delivering films on time and under budget, and Jackson has been superb at that,” says John Yeabsley, a senior fellow at New Zealand's Institute of Economic Research. “Nobody has the same record or the magic ability to bring home the bacon as Sir Peter.” Back in 2010, however, a labor dispute erupted before filming began on “The Hobbit.” Unions said they would boycott the movie if the actors didn't get to collectively negotiate. Jackson and others warned that New Zealand could lose the films to Europe. Warner Bros. executives flew to New Zealand and held a high-stakes meeting with Prime Minister John Key, whose government changed labor laws overnight to clarify that movie workers were exempt from being treated as regular employees. Controversies aside, the rise of Weta and the expat American community in and around Miramar is visible in everything from a Mexican restaurant to yoga classes. On Halloween, which in the past was not much celebrated in New Zealand, hundreds of costumed children roamed about collecting candy. Americans gave the tradition a boost here, but the locals have embraced it. The National Business Review newspaper estimates Jackson's personal fortune to be about $400 million, which could rise considerably if “The Hobbit” franchise succeeds. Public records show Jackson has partial ownership stakes in 21 private companies, most connected with his film empire. He's spent some of his money on philanthropy, helping save a historic church and a performance theater. For all his influence, Jackson maintains a hobbit-like existence himself, preferring a quiet home life outside of work. In the end, many say, he seems to be driven by what has interested him from the start: telling great stories on the big screen. — AP
