Heartstopper season 3 is heading to our screens later this year and the cast has now grown by three familiar faces. More on the news below. 


I think it’s than fair to say that Heartstopper has exceeded all expectations. The coming-of-age Netflix series was an instant hit when season 1 premiered in April 2022 and the success continued with season 2 in August 2023. 

Heartstopper season 3 will return to Netflix in October this year, with a firm date still to be announced. While it was recently reported that Olivia Colman couldn’t reprise her role for the latest run, the series has added some new faces to its growing cast. 

Eddie Marsan, Hayley Atwell and Jonathan Bailey have all joined the cast. Kit Connor, Joe Locke, William Gao, Yasmin Finney, Corinna Brown, Kizzy Edgell, Tobie Donovan, Leila Khan, Rhea Norwood and Jenny Walser are all returning to the series, reprising their earlier roles. 

“I am incredibly excited to be welcoming three new cast members to the Heartstopper family,” said Alice Oseman, the creator and writer of Heartstopper about the new additions to the cast. “Hayley Atwell joins the Nelson family as Nick’s Aunt Diane, who takes Nick on a summer holiday to Menorca and has some tough advice to impart about his relationship. Eddie Marsan will be portraying a beloved character from the graphic novels: Geoff, Charlie’s wise and straight-talking therapist. And lastly, Jonathan Bailey will be making a cameo appearance as Jack Maddox, an Instagram-famous classicist and celebrity crush of Charlie.

“It was an absolute joy to see Hayley, Eddie, and Jonathan’s talent alongside our existing cast, and I can’t wait for the Heartstopper fans to meet these new characters.”

Here’s also the official synopsis for Heartstopper season 3:

Charlie would like to tell Nick that he loves him. Nick also has something important to say to Charlie. As the summer holiday ends and the months race on, the friends begin to realise that the school year will come with both its joys and its challenges. As they learn more about each other and their relationships, plan social events and parties and start thinking about university choices, everyone must learn to lean on those they love when life doesn’t go to plan.

In an era where LGBTQ+ rights are still (unfortunately) a hotly debated topic, Heartstopper has felt like a soothing salve. It was unapologetically queer and romantic and never focused solely on the struggle of being queer, but instead celebrated it. 

We’ll keep you updated on more Heartstopper news when they arrive in our inboxes.
