FILM GENRES

(Dirks)

Main Genres

• Action – Usually include high energy, big-budget physical stunts and chases, possibly with rescues, battles, fights, escapes, destructive crises (floods, explosions, natural disasters, fires, etc.), non-stop motion, spectacular rhythm and pacing, and adventurous, often two-dimensional ‘good-guy’ heroes (or recently, heroines) battling ‘bad guys’ – all designed for pure audience escapism.
• Adventure – Exciting stories, with new experiences or exotic locales, very similar to or often paired with the action film genre.
• Comedy – Light-hearted plots consistently and deliberately designed to amuse and provoke laughter (with one-liners, jokes, etc.) by exaggerating the situation, the language, action, relationships and characters.
• Crime & Gangster – Developed around the sinister actions of criminals or mobsters, particularly bankrobbers, underworld figures, or ruthless hoodlums who operate outside the law, stealing and murdering their way through life.
• Drama – Serious, plot-driven presentations, portraying realistic characters, settings, life situations, and stories involving intense character development and interaction. Usually, they are not focused on special-effects, comedy, or action.
• Epics/Historical – Take a historical or imagined event, mythic, legendary, or heroic figure, and add an extravagant setting and lavish costumes, accompanied by grandeur and spectacle, dramatic scope, high production values, and a sweeping musical score.
• Horror – Designed to frighten and to invoke our hidden worst fears, often in a terrifying, shocking finale, while captivating and entertaining us at the same time in a cathartic experience.
• Musicals/Dance – Cinematic forms that emphasize full-scale scores or song and dance routines in a significant way (usually with a musical or dance performance integrated as part of the film narrative), or they are films that are centered on combinations of music, dance, song or choreography.
• Science Fiction – Often quasi-scientific, visionary and imaginative – complete with heroes, aliens, distant planets, impossible quests, improbable settings, fantastic places, great dark and shadowy villains, futuristic technology, unknown and unknowable forces, and extraordinary monsters (‘things or creatures from space’), either created by mad scientists or by nuclear havoc.
• War – Acknowledge the horror and heartbreak of war, letting the actual combat fighting (against nations or humankind) on land, sea, or in the air provide the primary plot or background for the action of the film.
• Westerns – A eulogy to the early days of the expansive American frontier.
