Being a Pittsburgh native, this film is legendary here, rivaled only Striking Distance for cultural relevance.
The reason they were able to get so many legendary Pens in there is two-fold: the league was on strike and the owner's wife wrote the script as a way to get herself started in Hollywood. There weren't enough fans in the game scenes, which originally were Chicago and Pittsburgh, but post-strike used the Johnstown Chiefs and Wheeling Thunderbirds, so if you go back and watch, most of the crowd are cardboard cutouts. Once you know that, you can't not see it. It takes over the screen.
There's a novelization that Powers Booth did the audiobook for that I've been obsessed with finding.
