Continuity mistake: When Doug and Kate are doing the short programme at the Nationals and they perform the side-by-side double axels, when Kate spins, the sole of her boot is wooden. When she lands the spin, it is black plastic.
Continuity mistake: In the scene where the coach comes to recruit Doug, Doug is hanging upside down hammering nails. The nails change position several times.
Continuity mistake: In the first training montage, Kate changes clothing for a split second. Initially she is wearing a red outfit with black legwarmers. She changes to green lycra pants and black legwarmers, then back to the red dress and black legwarmers. You can also see Douglas' grey hoodie is swapped for a red top. (00:23:55)
Continuity mistake: In the opening of the movie Kate has left her Olympic warm up early and is walking down the hallway in the arena. At the same time Doug is running down the same hallway to get to the Olympic hockey game that he is late to. He asks her "Does this go up to the ice?!" There is no way that Kate's practice was over in time for an entire arena of ice hockey fans to enter and already be into the 1st period of the game...yet she is still walking down the hallway or she is the slowest walker ever.
