I see few Americans in the credits. Did you mean absurdly following in the Hollywood style, or are the handful of Americans involved in that film enough to make it "Hollywood"? Genuinely asking. Is Hollywood a place, a process, or a result?
Very little of "Hollywood" is about the place today. Movies are often filmed outside of it for tax purposes. Referencing it is almost always about either the style or the clique of people who engender the style.
