As Deadline reports, Williams had no prior knowledge of tennis when he made a decision to start training his daughters.
Smith is now filming the highly-anticipated Bad Boys For Life with Martin Lawrence, and he is also attached to return for a sequel to Netflix's Bright.
In a new biopic spec script, King Richard, we learn the story of how Richard Williams overcame hardship and his own troubled past to help train his daughters to become two of the best tennis players in history. Smith will produce with Tim White and Trevor White, with Allan Mandelbaum and Caleeb Pinkett as executive producers. Serena won her first at the U.S. Open in 1999, and Venus got her first title at Wimbledon in 2000.
Smith was called the "Most powerful actor in Hollywood in April 2007" by Newsweek and was nominated for five Golden Globe Awards and two Academy Awards, and has won four Grammy Awards.
"Colorism matters.love will Smith but there are other black actors for this role" tweeted Clarence Hill Jr.
However, his casting has attracted criticism from film fans who insist the Independence Day actor is significantly lighter in skintone than the darker skinned Williams. The rapper-turned-actor is now shooting Bad Boys For Life with Martin Lawrence.
Smith is next up playing the genie in Guy Ritchie's live-action remake of Disney's Aladdin, due out in May.
