Continuity mistake: When the bobsled team is getting their act together in Calgary, there's a scene of them pushing off with an unpainted bobsled. In the shots of the feet of the guys pushing at the back of the sled, you can see that the lower back of the sled is painted black with green stripes, the colours that they paint the sled in a scene a few minutes later.
Continuity mistake: In Jamaica, when they are practicing with the roughly thrown together bobsled on the dirt road, right after they swerve to avoid the lady on the road and right before the bobsled crashes into the police vehicle, they are going over the rough terrain and the bobsled's front wheel (left side to the viewer) flies off in front of the bobsled from the left side of the screen to the right, but in subsequent shots of the bobsled the wheel is always there.
Visible crew/equipment: When Mr. Coolidge shuts off his TV after Jamaica's first bobsled run, a stage light is reflected in the TV screen.
Revealing mistake: The first scene where they are trying their homemade bobsled, right after coach tells them they need 6 seconds flat, they use the same scene when Junior flips over the bobsled (3 times) but from different angles. Twice when coach is timing them and again right after where they are pushing coach in the VW bug. Junior flips over and lands on Brenner, and Sanka does the same 2 spins and lands on his knees.

Continuity mistake: While naming the bobsled "Cool Runnings", one can notice that the Coca-Cola bottles are constantly being switched among the team and coach. There are two types of bottles, some with red labels and others with the original white text design. You will notice that characters will hold 1 bottle and then suddenly it will be switched with the other. And the amount of coke in the bottles never seem to decrease despite them drinking.

Factual error: A shot of the Calgary skyline at night is displayed. The tall building on the left with the glowing roof is Banker's Hall. Also notice the building with the red logo, Canada Trust Tower, that is to the right of it. Neither of these buildings existed at the time of the 1988 Calgary Olympics. Bankers Hall wasn't completed until 1989, and the Canada Trust Tower wasn't completed until 1991. (01:25:16)
