Walt finds Leaves of Grass, Walt Whitman's book of poetry in a box as he moves back in to the house at the beginning of the episode.
Both Matt L. Jones (Badger) and Charles Baker (Skinny Pete) can play instruments in real life.
When Saul is showing the box factory, the trio talk about a corrugater machine. But Adam Bernstein, the director, notes on the podcast that this wasn't the real corrugater because it was out of place for shooting, but similar. Interestingly, Vince says he also worked in a cardboard box factory for a couple of days. The tortilla factory was not originally in the script, they found the location as they were scouting and Aaron added the part where he grabs the tortilla at the end. The crew had to buy out the factory during the shoot because of the cleanliness restrictions.
In the episode podcast, the team says that new hazardous materials suits were used in this episode because the Tyvek ones from the previous season were noisy and very hot. This was the result of the new costume department manager. According to Vince, they were still really hot but they shot all of the teaser images with them.
Mike: Just because you shot Jesse James, don't make you Jesse James.
