One that I enjoyed was "The Greatest Game Ever Played", and I am a little surprised it hadn't been mentioned previously. Given the fact it was based on a true story, that of early golfer Francis Ouimet, I think they done a great job on it.
Think I watched it on Netflix a few years ago, couldn't tell you if it is still on there.
Of course the ones mentioned previously in the thread would probably come ahead of this, but this one is definitely worth a watch if you haven't already seen it.
