There - Will Be Blood 2007

Anderson uses this period not for historical recreation but as a crucible to forge an archetypal American myth.

No one in the film is authentic. Daniel plays the "family man." Eli plays the "man of God." The landowners play at being independent. Anderson shoots business negotiations like theatrical duels. The final scene—Daniel alone, refusing to even perform sanity—is the only moment of truth.

The film is currently available on streaming services like Paramount+ and Amazon Prime (rental), and the 4K Criterion Collection release is the definitive physical version, featuring a brilliant commentary track by Paul Thomas Anderson.
