Tom McCarthy explained in an interview how he and Matt Damon immersed themselves in the culture of Oklahoma oil "roughnecks" for the film - "Matt and I started going to Oklahoma early on to get a taste of the place and the people and spending time with roughnecks, in particular. They really opened up their lives to us, and their worlds and their families. They were incredibly instrumental in helping us shape the story."

Towards the end of the film, Matt Damon's character plugs his nearly obsolete model iPod into a boombox, and makes himself coffee in a coffee machine. The product appears to be Folgers instant crystals freeze dried coffee, inconsistent with coffee grounds that would normally be poured into such a coffee machine. However the jar doesn't look like the freeze dried product. It is in fact Folgers 100% Colombian ground coffee.
