Short answers, pulled from the story.
Drama is classified as a narrative fiction intended to be more serious than humorous in tone, while comedy prioritizes humor. The Screenwriters Taxonomy treats both as broad "types" rather than genres, arguing that neither label alone is specific enough to describe a film's atmosphere, character, and story.
A documentary uses real people to describe history or current events, while a docudrama uses professionally trained actors to dramatize those same events. Examples of docudramas include Black Mass (2015) and Zodiac (2007).
Hypardrama is a sub-type of drama coined by film professor Ken Dancyger, describing stories that exaggerate characters and situations to the point of becoming fable, legend, or fairy tale. Fantastic Mr. Fox (2009) and Maleficent (2014) are cited as examples.
The Screenwriters Taxonomy classifies drama as a "type" of film rather than a genre, arguing that "drama" and "comedy" are too broad to function as genres. It identifies at least ten sub-types and recommends combining the type with one of eleven super-genres to describe a film precisely.
Melodrama is classified by the Screenwriters Taxonomy as a pathway rather than a genre or type. Its plots appeal to heightened emotions, often dealing with failed romance, strained family situations, illness, or emotional hardship, and critics sometimes use the term pejoratively to describe unrealistic, pathos-filled stories.
Docufiction combines documentary footage of real events with recreated scenes, intermingling actual footage with fiction. A docudrama, by contrast, uses actors to dramatize real events without incorporating actual documentary footage. Interior. Leather Bar (2013) is listed as an example of docufiction.
