When I first heard the plot synopsis for "The Will Be Blood" I had wondered if it would be a fictionalized version of the Doheny family story--- Well, there are some elements, as Upton Sinclair (who wrote the original novel OIL! was no doubt familiar with those shady goings-on by then, but it's NOT a Doheny bio-pic. Even so, it IS fitting that they DID film some scenes in an authentic mansion built by one of the most notorious CA oil moguls of that era.
