I agree the movie fell short of what it might have been. It would be great if a film maker who really loved hunting and the shooting sports were to make a similar movie. I'm not sure such a person exits in Hollywood.
If any of the regular posters on this forum had made that film, a firearm or firearms would have survived the crash. It would have been clearly demonstrated how hunting skill and marksmanship really could be the difference between life and death in a wilderness survival situation.
Forget that particular movie for the sake of the hypothetical question. If you were to survive a plane crash in the remote wilderness like Alaska or Canada, what handgun and rifle would you want at the ready both to obtain food and for defense against 4 or 2 legged predators?
