Rabe is an excellent playwright -- I'll have to check this out. Movies adapted from stage plays are great places to find good dialog, in general. Other examples: A Thousand Clowns, Angels in America.
I think this might be a reply to a different comment (about Hurlyburly maybe?). The screenplay for Glengarry Glen Ross was written by David Mamet (another excellent playwright, btw), adapted from his play of the same name.
"The Image" by Daniel Boorstin. It's kind of about what living in a world of mass-produced images does to our sense of space, time and reality. So much of our experience is of things that were created by other people to persuade us to do something, and that's a pretty recent thing.
