4. Apocalypse Now (1979)
There’s a school of thought that trying circumstances tend to bring out the best in the most talented filmmakers, and that most definitely applies to Francis Ford Coppola’s Apocalypse Now.
Wildly behind schedule and massively over budget, everything that could have gone wrong during the production did, but the director still came out on the other side with an all-time great movie.
Coppola paints a haunting and harrowing portrait of the Vietnam War, and gets the themes and messages across through the experience and actions of the characters instead of relying on obvious allegory for dramatic effect.
