When it came time to name the two lead characters, Kripke decided on "Sal" and "Dean" as an homage to Jack Kerouac's road-trip novel "On the Road". However, he felt that "Sal" was inappropriate for a main character and changed the name to "Sam". It was originally intended for the brothers' last name to be "Harrison" as a nod to actor Harrison Ford, as Kripke wanted Dean to have the "devil-may-care swagger of Han Solo". However, there was a Sam Harrison living in Kansas, so the name had to be changed for legal reasons. Combining his interest in the Winchester Mystery House and his desire to give the series the feel of "a modern-day Western", Kripke settled on the surname of "Winchester". However, this also presented a problem. The first name of Sam and Dean's father was originally "Jack", and there was a Jack Winchester residing in Kansas, so Kripke was forced to change the character's name to "John".
