I don't have my copy of the Premiere anymore. I did find the article quoted online, which speaks a bit to the filming conditions:
Here's a quote from Premiere Magazine, July 1993
Craig Fincannon of Fincannon & Associates, who did some of the casting for The Crow, says Willmington, NC, is an ideal place to make movies (paraphrased). Translation: it's a place to make movies cheap), the Hollywood equivalent of making tennis shoes in Taiwan. While many workers in Wilmington are as highly trained as their brethren in New York and L.A, North Carolina is a right-to-work state, no unions necessary. Wages are lower, rules relaxed, and there are no fringe benefits to pay. Producers can save 20 or 30 percent on labor costs. It's one of the big reasons why North Carolina was second in film production revenues in the United States in 1990, pumping more than $400 million into the local economy. Fifty features have been shot there since 1983, including Super Mario Bros, and the forthcoming Hucksucker Proxy. And with the current trend in Hollywood toward independent films, the whole place is beginning to smell like a boomtown. But for many in Wilmington who make their living in the movie business, it's a mixed blessing. They all know the main reason producers come here is that it's cheap and workers have no recourse against demands for long hours and low wages. "You know that sometimes you're being exploited," says one Wilmington veteran. "But nobody wants to stand up and say anything about it for fear of scaring business away." Attempts at unionizing have been rebuffed. "The real problem is that people down there believe that if they start to demand higher wages and better working conditions," says Bryan Unger, an organizer for the International Alliance of Theatrical Stage Employees in New York, " they'll stop making movies there." (This same fear, [in] fact [is ]the reason most crew members on the production declined to be quoted by name for this article.)
