In "God's Pocket," Philip Seymour Hoffman is Mickey who lives in a poor neighborhood called God's Pocket with Jeanie, played by "Mad Men" cast Christina Hendricks. However, when his stepson dies in an accident at a workplace, Mickey's life unravels with his mounting debts, an ever disgruntled wife and the body of his stepson which he couldn't bury.

Christina Hendricks also shared to E! her experience working with John Slattery, who plays Roger Sterling in "Mad Men," saying that she would be shooting a YouTube video in his backyard if he just asks "but this ended up being a lot better."
