The keyword phrase functions as a compound noun. In this construction, "Patriots Day film" serves as the primary noun subject, which is being modified by the postpositive adjectival phrase "behind the scenes." The entire term collectively names a specific subject or category of content: the making-of or production process of the specific motion picture.
As the main point for an article, this noun classification is critical because it establishes the subject matter, not an action (verb) or a quality (adjective). The article's core purpose, therefore, would be to explore and present a body of information related to the film's creation. This includes topics such as pre-production planning, directorial choices, interviews with cast and crew, special effects breakdowns, location scouting, and the logistical or ethical challenges of dramatizing the real-world events depicted.
Consequently, an article centered on this keyword must be expository in nature, focusing on the "what" and "how" of the movie's production. The main point is the collection of unrevealed facts, processes, and anecdotes from the creation of the cinematic work. The structure of the article should be built around describing these elements, rather than arguing a thesis or narrating an event in a linear fashion. The keyword's function as a noun dictates that the content's purpose is to inform about a specific, named concept.
