If asked if he had a certain longing for loneliness considering his roles in Brokeback Mountain and Jarhead, Jake Gyllenhaal would say, "I don't know if it's a longing for it, it's just something that I relate to. I didn't realize, either, that it was going to be that lonely until we got out there. Both Jarhead and Brokeback Mountain, the topography of both of the areas was desert and flatland and then huge mountains. It was nothing but nature around and your own mind. So I don't know if I really understood that that's what it was going to be. When you read the script, you're like, 'Oh, cool. I get to ride horses!' -- and then you're like alone for three months."
