Just a note, the 2015 Australian movie Oddball and the Penguins is available on Netflix DVD. No streaming as of yet. It's a good family movie. It's about Maremmas, which have many similarities to Kuvasz. Also on the DVD is an hour-long documentary that describes the real-life project, which was just as interesting as the movie: it took 6 years of persistence and determination by Swampy Marsh to see his vision realized.
