Avalanche (1978)
Lousy little disaster movie. Our two big name stars, Rock Hudson and Mia Farrow, are a divorced couple, although he doesn't seem to accept that fact. She shows up at the ski resort he runs. Also present is Hudson's fun-loving Mom (veteran character actress Jeanette Nolan.) There are also skiers, snowmobilers, skaters, etc. For about an hour, we get some stuff about Hudson being in legal trouble for some vague reason, as well as a couple of love quadrangles. (Love quadrangle one: Hudson, Farrow, Nature Guy who warns Hudson that there's gonna be an avalanche, and Hudson's secretary. Love quadrangle two: TV sports announcer, his wife, hot shot skier, and figure skater.) In addition to all this soap opera stuff, we've got lots of scenes of skiing, skating, snowmobiling, etc.
Finally we get the avalanche, which is played by animation and foam blocks. It's caused when a plane flying through bad weather, carrying some guy involved with Hudson's vague legal problems, crashes into a mountain. Some decent stunt work here, I'll admit. Some folks live, some folks die, you won't care which ones. None of the legal or romantic subplots are resolved.
Not a good movie. Some footage from it was used in another bad disaster movie, Meteor.
