Director: Dexter Fletcher
"Based on a true story" is more or less Hollywood speak for "we got the three things you remember about this event right, and everything else doesn't bear up to a quick Wikipedia check". It doesn't mean this or others movies aren't worth watching, but always always always Google the subjects of "true story" movies after finishing a film. It's inevitably more interesting than what's in the movie.
I do not remember the 1988 Calgary Olympics at all. I was 13 and lived in Texas where none of the sports existed, and didn't watch much TV at that time in my life. Jamie was actually at those Olympics, so she remembers the actual events and guy. I think I vaguely remember watching hockey.
Eddie the Eagle (2015) is a fine movie - a decent one for kids and adults. Unlikely guy goes to the Olympics to compete - and the glory is in trying. I've spoiled nothing - you can still watch. Everything is very color-by-numbers and has the edges removed. I mean, it's fine - I enjoyed it for what it was.
