Not a ski movie exactly, and we tend to watch it when it's blizzarding so bad that everything is shut--Ric Burns' "The Donner Party". A quote: "And it snowed, and it snowed, and it snowed." First time we showed it we got five feet at Donner Lake the first day, and 3 each the next 2 days. I80 was closed for 4-5 days. Nowadays we also watch it when we need snow but it seems to have lost it's mojo. I guess you can only rub the lamp so many times before the genie quits.
And BTW--the Donner Party never gets the credit it deserves for popularizing the paleo diet.
