Well, looks like watching movies is not a total waste of time after all. A 16-year old snowboarder who disappeared on a mountain in Utah, survived without proper cold weather gear due to knowledge he picked up in a movie.
The movie? Vertical Limit. The knowledge: build up a snow cave to keep yourself warm.
Luck is not a substitute for preparedness, however – next time, kid, bring a PSK (personal survival kit) when snowboarding.
