The High Five (2014)

On October 2nd, 1977 Dusty Baker hit his 30th homerun of the season. As Baker rounded the bases, an excited rookie named Glenn Burke met him at home plate, raised his arm high in the air and slapped Baker's hand. It was the first high five recorded in the history of sports. A year later, Burke was forced out of baseball amid rumours of his sexual orientation.

Unfortunately the movie The High Five is not yet available on HBO Max.
