Documenting another era in time

I just watched Harvard Beats Yale 29-29, a documentary about the 1968 football Game between Harvard and Yale. The game is one of the more infamous comeback stories from college football, with Harvard tying the score in the final seconds. Yale was heavily favored to win, and led for most of the game but then everything fell apart. “It was as if some spirit came into the stadium and turned everything around,” says one of the players interviewed in the film.
