The 55-year-old actor will join former 'Agent Carter' actress Hayley, 42, and 'Wicked' star Jonathan on the billing of the next instalment of the hit Netflix series, which follows the love story of Nick Nelson (Kit Connor) and Charlie Spring (Joe Locke).

Alice Oseman, creator and writer, said about the new cast members: “I am incredibly excited to be welcoming three new cast members to the 'Heartstopper' family.

"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."

The writer added that 'Back to Black' star Eddie will be appearing in the role of Geoff - a character lifted from her original graphic novel series - whilst Jonathan will make a cameo appearance of an Instagram celebrity.

Alice added: “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.”

As well as its two lead actors, William Gao, Yasmin Finney, Corinna Brown, Kizzy Edgell, Tobie Donovan, Leila Khan, Rhea Norwood and Jenny Walser will also be appearing in the show's latest batch of episodes.

The third series of 'Heartstopper' will consist of eight episodes and will premiere on Netflix in October 2024.
