Continuity mistake: The editing of the ski jumping competition is a disaster movie in itself: first we see #35 jumping and wearing a helmet while wearing a red and blue suit. Then comes #6, who starts to ski wearing a helmet and a marine blue suit, but when he jumps it's skier #35 again but now his helmet is gone. Now comes a new skier, #26, wearing a dark blue suit. When he picks up speed he is suddenly no-helmet #35 and -drumroll - when he jumps he's now yet a new skier, #27.
Continuity mistake: When David arrives to save Caroline who's hanging off the broken bridge railing, in the wide angles her feet are dangling and her arms are stretched, while she is struggling for her life.
