All three of the main love triangle in "How to Date Billy Walsh" are familiar faces, each fresh off the success of a recent beloved Netflix series. Charithra Chandran, who rose to fame as Edwina Sharma in season 2 of "Bridgerton", plays Amelia, while Sebastian Croft from the coming-of-age hit show "Heartstopper" plays Archie — two best friends who have been inseparable since childhood. As the eponymous Billy Walsh, Tanner Buchanan ("Cobra Kai", "He's All That") stars.
Beyond them, the supporting cast boasts a number of British comedy icons such as Lucy Punch ("Motherland"), Guz Khan ("Man Like Mobeen"), and Nick Frost ("Hot Fuzz"). As well as this, "The Big Bang Theory" star Kunal Nayyar features, and the cast is rounded off by newcomer Daisy Jelley.
Tushar Jindal, head of film acquisition at Prime Video, said, "How to Date Billy Walsh" features an incredibly exciting, young, and diverse cast that have already made a mark internationally."
