Makeshift Families
Anderson's characters tend to be lost souls who come together and form a family unit. Way back in his debut feature Hard Eight, mysterious old gambler Philip Baker Hall teaches lonely, boyish John C. Reilly how to be a gambler and, in the process, essentially adopts him. That's a relationship mirrored by Burt Reynolds' porn director and Mark Wahlberg's burgeoning star in Boogie Nights, and seen again in There Will Be Blood when Daniel Day-Lewis's oilman Daniel Plainview adopts the orphan H.W. as his son (and business partner).
