The Derrick Fire There Will Be Blood

The gas blowout and derrick fire — beat 13 in the 40 Beats — is the film's pivotal sequence: the moment when Plainview's oil strikes, his son is deafened, and his priorities are permanently exposed. It was also the most dangerous and technically demanding scene in the production, the only fully storyboarded sequence in a film that otherwise thrived on spontaneity.

The blowout deafens H.W. and exposes Plainview's priorities

The gas eruption comes without warning. Workers scramble to extinguish lights. H.W. is thrown from the derrick platform; Plainview rushes to him, pulls him down, and carries him to shelter. The boy cannot hear — "I can't hear my voice." But Plainview's attention splits immediately. He tells H.W. to wait, promises to return, and runs back to the burning derrick. He smashes the cables with a hammer to prevent the fire from spreading. Then, standing before the inferno, he delivers the line that captures his character in a single breath: "What are you looking so miserable about? There's a whole ocean of oil under our feet! No one can get at it except for me."

The fire confirms the gusher. The gusher deafens his son. Plainview chooses the gusher. Everything that follows in the film — the abandonment, the baptism, the bowling alley — traces back to this moment when Plainview decided what mattered.

The fire was the only storyboarded scene in the film

Anderson and Elswit storyboarded the derrick fire with military precision because the sequence could not be repeated. The fire would be real — a full-scale controlled burn of the constructed derrick — and once it started, the production would have one chance to capture the footage.

The fire burned hotter than anticipated and could not be fully controlled. The derrick collapsed before all desired shots were captured, including a planned 200-foot overhead angle. The smoke was visible for miles, forcing the Coen Brothers' No Country for Old Men crew, shooting nearby in the same West Texas landscape, to shut down production for a day. (alltherightmovies)

Anderson described the pyrotechnics crew's warning before the burn.

"There's no — I cannot guarantee that I can put this fire out. I can do it and I can turn it off, but once that derrick catches on fire, there's a chance I might not be able to put it out." — Paul Thomas Anderson, recounting the pyrotechnics crew, Fresh Air (2008)

Tichenor constructed missing angles through editorial ingenuity

Because the fire consumed the derrick faster than planned, editor Dylan Tichenor lacked complete coverage. He constructed additional angles by punching into different takes — isolating portions of wider shots and using repeated action cuts to add velocity where the original footage fell short. The technique gives the sequence its chaotic energy: the editing mimics the fire's unpredictability.

"The cuts that are more nerve-wracking to me are the slower, quieter ones. There's a big spotlight on, 'Now I'm changing perspective; now I'm showing you something else.'" — Dylan Tichenor, No Film School

Tichenor also pushed Anderson for more reaction shots of H.W. throughout the film, recognizing that the boy's perspective was essential for maintaining audience empathy with an otherwise repellent protagonist. The derrick fire sequence is where this strategy matters most: H.W.'s terror provides the emotional register that Plainview's exhilaration deliberately withholds. (nofilmschool)

The sequence briefly enters H.W.'s subjective perspective

When the explosion deafens H.W., the film does something it does nowhere else: it shifts point of view. Sound drops away, replaced by a high-pitched tone. For a brief passage, the audience hears what H.W. hears — nothing — while watching Plainview move and shout in silence. This is the only sustained subjective sound design in the film. Every other scene is presented from Plainview's perspective or an objective third-person position. The shift to H.W.'s deafened perception tells the audience that the boy's experience matters, even though Plainview's attention has already returned to the oil.

Day-Lewis broke a rib in the mine shaft scenes that precede the fire

The physical reality of the production matched the physical reality of the character. During the opening mine shaft sequences filmed at the Presidio mine in Shafter, Texas, Day-Lewis broke a rib. Anderson's response: "Now we're making the movie." The injury established the production's ethos — real danger, real physical cost — that the derrick fire would extend to its most extreme point.
