This is somewhat late to the party, but three years later I still haven’t seen this argument made anywhere else, so here goes.
Many critics have noted that Daniel Day-Lewis‘s performance in There Will Be Blood (2007) drew heavily from his fellow Irishman John Huston‘s turn in Chinatown (1974). See, for instance, here, here, here, and here. Or just compare for yourself:
…But that is only one level of mimicry. Paul Thomas Anderson’s feature itself is loosely based, structurally, on Stanley Kubrick’s 2001: A Space Odyssey (1968).
Now, I’m not claiming that Anderson consciously aped Kubrick’s masterpiece. And I don’t want to suggest that the films share identical or even similar plots (although there are some points of comparison). Rather, it is the manner in which There Will Be Blood presents its respective story that it borrows from 2001.
