I began my evening by watching the bonus material on the second disc in the THERE WILL BE BLOOD set. Not much there actually, less than an hour's worth of material all told.
There were a couple of deleted scenes, one outtake, a 15 minute montage of the still photographs, newsreels, and films that gave Paul Thomas Anderson the look and feel for the movie prior to filming, two trailers, and a 26 minute silent movie (with a new score) called "The Story of Petroleum," made in 1927 which is when the events of the film conclude.
