- Ascended Fanboy: Many of the American hockey players had grown up hearing about/being inspired by the original game - particularly Billy Schneider, as his dad Buzz had literally been a part of it - and so were quite enthusiastic to partake in this film's recreation.
- Cast the Expert: From the beginning, the film crew looked for hockey players they could teach how to act, because trying to do the opposite would've been flat-out impossible. As a result, nearly all of those cast as hockey players had at least played at the major college level.
- Enforced Method Acting: To make the scene where coach Herb Brooks drills the team all night (after their 3-3 tie with Norway) as realistic as possible, the director filmed the real actors skating the drills for three 12-hour days. Their reactions (including collapsing from exhaustion and experiencing dry heaves) were genuine.
- Fake Russian: Sarajevo-born Zinaid Memiević portrays the Soviet team captain Viktor Tikhonov.
- In Memoriam: The real Herb Brooks served as a consultant for the film's production before he died in a car crash six months prior to the film's release. There is a dedication for Brooks during the film's ending credits:"He never saw it. He lived it."
- Real-Life Relative: Buzz Schneider was portrayed by his son Billy.
