Hidalgo was truly a story Hopkins told and the movie was based on that. Seriously though, I think that movie was what really broke the "based on a true story" thing for me. There's no real criteria for claiming something is based on a true story, you only need a tenuous grasp to reality. Basically, you can make the claim that Avengers Endgame is just as much based on a true story as Hidalgo if you wanted to.
