Eric Kripke : "When we started casting, we had archetypes in mind, which were Han Solo and Luke Skywalker. We were really looking for Sam to be empathetic, kind, and likeable, and really the audience surrogate. The person who the audience would most see themselves as and really carry the story through their eyes. And that required a really unique likeability. For Dean, we were looking for Han Solo. We were looking for devil-may-care, charismatic, a little rough around the edges, a little edgy, says things that are not always the kindest thing, as long as they're funny. And that was really what we started out with."
