Jessica Biel and Justin Timberlake's eldest son has 'really cute' cameo in Matchbox: The Movie

Jessica Biel said Justin Timberlake’s eldest son Silas, 11, has a brief but “really cute” cameo at the end of Apple TV’s Matchbox: The Movie. Biel, 44, and former professional wrestler John Cena, 49, star in the film as it follows Cena’s character, spy-and-ex-soldier Sean Walker, and his childhood friends trying to find a nuclear warhead and clear their names after being blamed for a theft. Biel told E! News that Silas plays a small part, while his younger brother Phineas, six, joined the set. She described how both boys were fascinated by meeting their hero, though Phineas was confused about what was real on set, especially after Cena’s staged “punch.”
