Serena and Venus Williams have had a busy few weeks leading up to the release King Richard -- a film based on the role their father played in their careers. The legendary duo have attended the premiere and a series of promotional events for the film, which hit the screens on November 19.

The film, told from the perspective of their father Richard, focuses on the duo's formative years. Saniyya Sidney and Demi Singleton's portrayal of Venus and Serena Williams has earned them plenty of praise from all corners.

Venus Williams, for her part, seems to agree with the assessment. The seven-time Grand Slam champion recently took to social media to express her delight at the film's cast.

Williams shared an old photograph of her from when she was 10 years old, putting it up next to a picture of Sidney holding a racket from one of the scenes in King Richard.

The former World No. 1 described Sidney as "kind of perfect" for the role of her 14-year-old self, before complementing the young actress's on-court skills as well.

"Me at age 10 in Compton California. Saniyya Sidney as me in 'King Richard' film. She’s kind of perfect as me, and is a good tennis player as well," Venus Williams wrote on her Instagram post.
