Eddie exchanges his regular green skis for navy blue jumping skis. In the next scene, the green skis appear a few times in the crash montage.

In the Norway gym, Bronson draws something dropping out of the last skiers' pants. A minute later the same board is in view, but without the 'droppings'.

During several of Eddie's jumps and most notably his final 90m attempt, the advertisement on the underside of Eddie's skis changes during the jump as the camera shot cuts back twice in a slow motion shot. The advertisement changes from "Fischer" to "fleuge.de", both of which are commonly seen on modern day jumping skis, not on skis of the time.

Eddie changes his skis and has a second attempt at the 40m jump. There is a montage of crashes, his skis change back and forth from his original green ones to his newer white ones.

When Matti Nykanen lands on a K70 slope, it is shown he landed at 114,2 meters. In ski jumping the results are only measured in half meter. Also it is impossible to jump that far on a K70 slope.

When the Calgary ski jump event is presented on television, Matti Nykänen is spelled correctly based on Scandinavian alphabets. In reality international competitions use AE instead of the actual letter Ä. Therefore Matti Nykänen was actually spelled in the international competitions as Matti Nykaenen. This has always been funny to Finnish people especially when there are more than one Scandinavian extension letter like the 80's cross-country skiing Olympic champion Marja-Liisa Hämäläinen whose last name was always spelled Haemaelaeinen before she got married.

Eddie actually did not go to Germany for ski jump training. He went to Lake Placid, New York and was trained by Americans John Viscome and Chuck Berghorn.

The film is set in 1987 and Eddie ends up in hospital. However on the wall on at least one occasion is a modern hand sanitizer, not available in 1987.

When Eddie is in the German hospital you can see that the sink has two water taps (one for cold, one for hot water). This would be very uncommon for a German place as nearly everywhere there the sinks have only one mixer tap.

In several scenes the Olympic logo only contains 4 rings instead of the official 5, this was actually used in the arenas at the actual games. Four rings were made to form the number '88, the year in which the Calgary games took place.

The nose piece of the 1972 Pontiac Firebird that Bronson Peary works on has 4 scalloped headlight recessions, which first appeared on the 1979 model. This is consistent with the time line of the movie. The scene in question is set in winter 1987. Moreover this car make has been subject to car customizing regularly, so a '79 nose mounted on a '72 model is well possible.

Establishing scenes during Eddie heading to Europe in 1987 have the Deacon Blue song REAL GONE KID playing over the top. Whilst it fit in with the mood of the scene quite nicely, this tune was not actually released until Autumn 1988. It doesn't really exist within the movie; it's for the audience's benefit.

The ski jump competitions Edwards took part in at the Calgary winter games were held on two February days, 01:30 resp. 02:00 PM local time. Given the time difference of 7 hours, in England it was around or even after sunset when it was Edwards' turn. Nevertheless in the movie, when his parents in England are watching him jump live on TV, bright sunlight is shining through the windows in the background.

In many scenes, Eddie's glasses show no prescription lenses.

Eddie's mother hears him saying hi on the TV but there is no microphone on the camera at the landing site of the slope.

At the 1988 Calgary Olympics, ski jumpers have their skis "v-style" (tips spread apart) while in the air. V-style ski jumping came to competition in the 1990s. At the Calgary Olympics, ski jumpers kept their skis parallel in the air.

When the British national team is introduced to the press, their skis are short, with cut sides and rounded tips. Those skis first appeared in the mid 1990's.

When Eddie's parents are watching the 1988 Olympics, you can see VHS copies of Black Rain (1989) and In the Line of Fire (1993) in their little cabinet under the television.

In an early scene with Bronson Peary, a license plate on the wall says California in script letters. California first issued those plates in 1993.

Ski jumping hill in-runs were made of ice/snow in those days. Such modern in-run tracks appeared well after 2000.

The Calgary mountain scene shows Alpspitz and Zugspitz, 2 German mountains.

Toward the end of the movie, Calgary's ski jumping arena is actually Erdinger Arena in Oberstdorf, Germany.

The British commentators on Nykänen say that he is a person who lets his jumping do the talking. Matti Nykänen was well-known for being outspoken and as a person who spoke well more than needed.

In a voiceover, the Jim Broadbent character refers to ski jumping as an Alpine event, it is in fact, a Nordic event.

When Eddie is celebrating his first jump off the 70m at the Olympics, the frequently visible Finland flag that says "Flying Fin to win" is not the Finnish flag, as the cross of a correct Finnish flag is not centred. There are multiple Finnish flags throughout the movie that are correct, but this one is not. A more correct version of the Finnish flag can be clearly seen when Eddie's jump distance is being shown. In addition, a person who is from Finland is is a "Finn", with two n's.
