David (Josh Wiggins), an urban teenager, journeys to rural Montana to hunt big game with his estranged, "off the grid" father, Cal (Matt Bomer). As they ascend deep into the wilderness, father and son struggle to connect on any level, until a brutal encounter leaves them both with serious injuries, forcing them into a struggle to survive. Based on the American short story "Walking Out."
According to the directors Christian Bale was almost cast in the role of Cal. Ultimately Bale decided against playing the part because he didn't want to spend time away from his family in a remote location so soon after the birth of his second child. See more »
Cal (Matt Bomer) tells David (Josh Wiggins) not to eat snow, as it takes more water to process snow into water, than the snow gives you, calling it a sure way to dehydration. This is incorrect. All one needs to process snow into virtually pure water, is heat, and very little of that, which the body readily provides. Eating frozen snow could, however, contribute to, or hasten hypothermia, especially in a state of compromised health, extreme cold, and diminished caloric intake.
Cal (or the screenwriter) may have confused eating snow with drinking seawater, which does take more water to process than it provides, to remove the salts, and will dehydrate a human body. See more »
What if it keeps snowing? Or we get lost?
You worry too much. Like your mother.
I'm just not used to being so... Remote.
Well, you're not remote. You're with me.
