The film, directed by Paul Thomas Anderson, was released in 2007 and is known for its powerful storytelling and strong performances.

"There Will Be Blood" is not a direct true story but is loosely based on Upton Sinclair's novel "Oil!" published in 1927. The film, directed by Paul Thomas Anderson, follows the fictional character Daniel Plainview, a ruthless oilman in the early 20th century. While the characters and events are inspired by real historical elements of the oil industry and the era, the specific narrative and characters are largely fictionalized. The film explores themes of ambition, greed, and family dynamics within a dramatized context.

No, Paul and Eli are not the same person in "There Will Be Blood." Paul is the brother of Eli Sunday, who is a key character in the film. Eli, portrayed by Paul Dano, is a charismatic preacher, while Paul, played by the same actor, is a more minor character who appears briefly. The film uses both characters to explore themes of ambition, power, and moral conflict, particularly through the relationship with Daniel Plainview, played by Daniel Day-Lewis.
