"It means we have to audition and cast 60 to 80 actors to do the parts in each country, and we're in 30 different countries...We listen to them and approve them, but that can take a long time because there are maybe four to five actors for each part in each country. It takes a good day to really analyze everybody for one country -- if you have 30 countries, that's a month, and the only way you can do it."
