Character mistake: When Casey is using her knowledge of physics to advise a figure skater, she states, "Pull your arms in real tight. That increases your moment of inertia". In fact, this is the exact opposite of how it really works. Reducing her overall radius makes her rotational inertia smaller. (00:21:05)
Character mistake: When both Casey and her friend are watching the skater on tv, towards the end, when the musical theme starts, her friend's head twitches toward her, and it shows that she knows the script and is waiting for Casey to say her line.
