I saw this movie when I was 22. And I just saw the movie again at 52. I have seen it a few times in the past 30 years, and at 52 I think the movie is a great as it was when I was a kid just out of college.
I am a skier and snowboarder, and I watch and love the Warren Miller films (may he rest in peace). I also watch and love "Hot Dog... The Movie" because it has great scenery, awesome skiing (though I don't understand the ski ballet bit, no wonder it never made it into the Olympics), epic partying, and the most awesome T&A. Yes, us 50 year olds still love the T&A.
I have a Warren Miller film collection, and "Hot Dog... The Movie" sits right there alongside the them as a favorite ski theme movie that I plan to pass down to my children. Along with the Warren Miller films, of course.
