His experiences in the Yukon not only served as a major journey of self-discovery for London, but also would plant the seed for his literary career.

Here are the ways in which The Call of the Wild has its foundation in history. The Call of the Wild is primarily concerned with telling a compelling story and uses its history more as a basic framework to build upon, with the historical details mainly in the service of providing a setting for the story. While telling a fictional story, The Call of the Wild nevertheless has its basis in the period in which it is set, along with the life of Jack London and his experiences during the Klondike Gold Rush.

Given the adventurous nature of the story, this approach makes it significantly easier to fully realize the novel without putting actual dogs at risk.

Unlike past movies based on London's book, the latest version of The Call of the Wild brings the famed sled dog Buck to life via CGI, with Harrison Ford assuming the role of the novel's human protagonist, John Thornton.
