Good morning HHSE friends - for your convenience, we have linked below a handy-dandy list of "film genre" categories as commonly used in the entertainment business to track box office results of different types of films.
"ON ANY SUNDAY: THE NEXT CHAPTER" is a general interest documentary. It is not a "nature" film or a "politically-themed" film. It is a documentary. In its direct category, it very well could be the top grossing film of the year. When compared to other categories for which it is not applicable, then this would not be the case. For instance, some might characterize "THE AVENGERS" as an action film... whereas the industry considers it a superhero film. Yes, it has action and elements of an action movie, but the primary characters are superheroes - bigger than life - and this results in a more specific categorization.
