There are few things in life more inspirational and uplifting than a good old-fashioned sports movie. The underdogs overcome seemingly insurmountable odds, winning the big game and sticking it to the more traditionally athletic/wealthy/Russian rivals (seriously, when it's an international competition featured in a sports film, the villain is almost always Russia or a former USSR satellite).
But in pursuit of a feel good, come from behind victory, filmmakers have a tendency to bend the conventional rules of reality. Sometimes you see that "Based on a True Story" descriptor and think, "Really? Is it really?"
Because let's face it, you could make a film about the Battle of Ypres cast entirely with penguins and claim that it was based on a true story - hey, the battle did happen, didn't it?
But the worst offenders are films that don't just bend the truth, they come up with nonsensical plot lines that could never actually happen by any stretch of the imagination, and are just offensive to anyone who either plays or watches the sport in question.
