The film, which was shot in Spain, needed thousands of Chinese extras, and the company sent scouts throughout Spain to hire as many as they could find. The result was that many Chinese restaurants in Spain closed for the duration of the filming because the restaurant staff - often including the restaurant's owners - was hired away by the film company. The company hired so many that for several months there was scarcely a Chinese restaurant to be found open in the entire country.
