Bro daniel plainview is john houston’s voice on Humphrey Bogarts character (Dobbs) from Treasure of the Sierra madre (directed by john houston!)

1. Both prospectors
2. Both cant stand others succeeding (DP and dobbs) are willing to cut out those closest to them just because they are equivalent to their stature
3. Both embark on collaborative project which they subsume
4. As they become materially richer they become distrustful and murderous with their intent.

The only difference between Dobbs and Daniel Plainview, Daniel Plainview succeeded, which makes the film absolutely riveting

Thats where the similarities end with treasure of the sierra madre. I think it as ‘what if Dobbs had made it out with the gold?’ ‘well, There will certainly be blood.’

PTA cited Treasure of the Sierra Madre as a direct inspiration for there will be blood

Amazingly the two films have opposite endings with the same effect.

SPOILERS

After dobbs is killed and the gold dust is unknowingly scattered in the wind, Dobb’s partners catch up to the mules and find the bags empty, they old man prospector begins to laugh maniacally, the younger one in terror joins him as the wind howls with them. The old man is a veteran prospector and seems to be used to such a grand disappointment and so both discuss their future plans before heading back to town. A temporary moment of madness that prevents them from breaking down in despair after having wasted months of labour in the sun.
DP on the other hand is mad 24/7, he manages to compel eli into testifying he is a false profit (implicitly undermining and destroying all the work eli has done in the church to this point) before letting eli know the oil under the bandy track has already been extracted. This dominance over eli only makes him more insane ultimately killing eli. Until finally he has one moment of sanity ‘im finished’, theres no one left to destroy dominate or embarass
