American films dominate the market in nearly every country, regardless of the native language.
The most notable example is Luc Besson, who makes very French films, but in English so that they have a better chance of international success. In case you need a refresher in European history, I'll recap the story of Jeanne d'Arc. As a young girl, she had visions of leading France to victory against an invading England. Henry IV of England was to inherit France after the death of their king. But, they died at about the same time, so France's sovereignty was in question during the early 15th century.
