The Williams family couldn't afford a tennis coach for both Venus and Serena, so when Venus was training, Richard would film her sessions. Later, Serena would watch the tapes. This meant working with her mother, which Serena said was very difficult, but ultimately rewarding, "In hindsight, she really prepared me mentally on so many things and I had to just have a lot more tenacity than I thought I could have ever had," said Serena to USA Today.

Serena displayed said tenacity at a young age when she signed herself up for a tennis tournament without telling her parents. At the time, Venus was doing very well in the junior tennis circuit, but Serena was not there to watch.

Her parents soon realized she had entered a competition and was playing on a nearby tennis court. Instead of getting in trouble, it only made her father realize how much she wanted to play, a feeling both sisters carried throughout their lives.

King Richard is currently playing in theaters and streaming on HBO Max.
