ARGO (2012) is nominally about geopolitical entanglement in the Middle East, including several references to oil. However, it also makes an insightful observation about coal.
In the 36th minute, Lester Siegel (a famous movie director played by Alan Arkin), makes the following observation about Hollywood: “It’s a bulls**t business. It’s like coal mining: you come home to your wife and kids and you can’t wash it off.”
Who knew coal mining and film-making were so similar?
