Apparently, the marketing in North America is focused in fly over states, not in the big cities. It's being promoted on country music stations and rural America. Here in Los Angeles there are no billboards, no bus ads and no local tv ads. I go to a lot of movies 2 or 3 a week and I never seen a LL trailers at the theater. But l have seen a stand up poster.
I don't think they are looking for the GA, they sold oversees distribution rights that paid for the movie budget and Amazon cover the marketing budget for exclusive first right to the VOD streaming.
Steven Soderburgh is a genius, LL is going into the theater with little or no negative cost.
