By the 1970s and 80s, documentaries began focusing on the grueling reality of production. Notable examples include Hearts of Darkness: A Filmmaker's Apocalypse (1991), which chronicled the chaotic production of Apocalypse Now , and Burden of Dreams (1982), which followed Werner Herzog's obsessive struggle to film in the Amazon.

These documentaries do more than just inform; they frequently drive social and corporate reform.

Modern documentaries often function as investigative journalism, highlighting problems like the draconian movie rating systems in This Film Is Not Yet Rated (2006) or the grueling work hours and sleep deprivation faced by crew members in Who Needs Sleep? (2006). 2. Major Themes and Key Films

The personal lives and legacies of industry icons like Lucille Ball or Marlon Brando. Visions of Light (1992), The Cutting Edge (2004)

Early 20th-century portrayals often romanticized Hollywood as a magical place of constant sunshine and high salaries.

Issues of gender discrimination, LGBTQ+ representation, and systemic bias. From Bedrooms to Billions (2014), After Porn Ends (2012)

The genre has shifted from early promotional reels to deeply investigative and philosophical works.

By using personal audio recordings and home movies, such as in Listen to Me Marlon , filmmakers provide an intimate look that humanizes larger-than-life figures.
