There is a series on Netflix called “Luck” and it is about horse racing. Amazing photography right in the face of the running horses. Not for the faint of heart.
There is also a great movie called “LET IT RIDE” which is the funniest movie about horse racing EVER. If you know people who love to go the races, you will love this movie. I promise. Richard Dreyfus really in a comic tour de force performance. Hate him politically but that boy can act.
Horse racing gave us our first motion pictures, trying to prove taht a racehorse does in fact leave the ground with all four hooves.
