passage: In January 1993, Jon Krakauer published McCandless' story in that month's issue of Outside magazine. He had been assigned the story and had written it under a tight deadline. Inspired by the details of McCandless' story, Krakauer wrote and published the more extensive biographical book Into the Wild (1996), about McCandless' travels. The book was subsequently adapted into a 2007 film directed by Sean Penn, with Emile Hirsch portraying McCandless. That same year, McCandless' story also became the subject of Ron Lamothe's documentary The Call of the Wild (2007).
 question: is the movie into the wild a true story?
