Will Smith has posted a first trailer for his upcoming turn as father and coach of tennis greats Venus and Serena Williams in King Richard.

Rather than being a biopic on the swinging sisters, it concentrates more on their childhood and the role that heir father played in shaping their careers.

Says Smith: “One of the greatest honours as an actor is to be able to celebrate someone’s legacy while they’re still here creating it. I’ve gotten to do it a few times in my career playing Chris Gardner and Muhammad Ali, and every time it’s a fulfilling and expansive experience beyond compare. So now, I’m proud to show you all our first trailer for King Richard, the story of the man who introduced the world to Venus Williams and Serena Williams. The origin story for some REAL DEAL superheroes!!”

King Richard lobs into Australian cinemas from November 18.
