Venus and Serena Williams' dad Richard was a 'lot more stubborn' than movie portrayed: Childhood coach Macci

Venus and Serena Williams' childhood coach Rick Macci recently claimed that the legendary duo's father and coach, Richard, was even more stubborn than what was portrayed in the movie King Richard. Macci, who worked extensively with Richard Williams in the early days of Serena and Venus Williams' careers, also expressed his admiration for Richard.

He was a lot more stubborn than the movie portayed and that is why I love this guy and father.RICHARD WILLPOWER!" Rick Macci wrote on Twitter.

After working on King Richard, the Williams sisters are now reportedly teaming up on a new movie. As per reports, Venus and Serena Williams have collaborated with Alexandra Milchan, who produced the Oscar-nominated movie Tar, for a movie roughly titled En Garde.

The feature film will be based on Jewell Parker Rhodes’ bestselling book Black Brother, Black Brother, and will tell the story of two biracial brothers.
