At around 22:00, Chappellet is seen readying to race downhill by setting his goggles, yet prior to this a big deal has been made of him setting his goggles. One expects to see him approach the starting line with goggles ready.
David does a U-turn while driving through his home town, and suddenly a car appears in the scene.
Just after the Olympic Downhill gold medal racers reach the finish line, an announcer says (in German) "please clear the course; the first racer will be down in 5 minutes."
During the challenge race between Johnny and Dave (when Johnny crashes) the two skiers first have a pair of red and black skis, but the next shot farther on down the course they both have red skis.
On Dave's Olympic run he has black skis at the starting gate and alternating red and black skis while on the course.
When Robert Redford and Camilla Sparv go skiing they used tape to cover up the 'Head' logo on Sparv's skis since as part of the plot, she works for a competitor. However, later when they are driving her Porsche, you can clearly see the 'Head' logo on her ski tip bottoms from the reflection in the car windshield.
Tires don't squeal on snow, yet Dave manages this when driving the Porsche.
At the Olympic Games, the last skier appears on the verge of defeating Chappellet, but crashes and his skies go flying off. Moments later the crashed skier is seen skiing down the mountain wearing his skies.
