Nick Nelson and Charlie Spring’s love story will reach its conclusion — at least, on Netflix — in the first trailer for “Heartstopper Forever,” the feature-length film that will wrap up the beloved “Heartstopper” storyline after its three-season run on the streamer. It will begin streaming on July 17.

Creator and executive producer Alice Oseman, who’s adapted “Heartstopper” from her series of bestselling graphic novels, is writing the screenplay, with Wash Westmoreland (“Still Alice”) directing. Stars Kit Connor (Nick) and Joe Locke (Charlie) are returning as executive producer. Also expected to return are co-stars William Gao (Tao), Yasmin Finney (Elle), Corinna Brown (Tara), Kizzy Edgell (Darcy), Tobie Donovan (Isaac), Rhea Norwood (Imogen) and Leila Khan (Sahar).

Since its debut in April 2022, “Heartstopper” has become a cultural touchstone, depicting the burgeoning romance between Charlie and Nick — as well as between Tao and Elle, Tara and Darcy, and Imogen and Sahar — with a forthright tenderness that has won over a legion of fiercely loyal fans. The show has also made Connor and Locke into bona fide stars: The former starred on Broadway in “Romeo + Juliet” with Rachel Zegler and in the visceral Iraq War film “Warfare,” while the latter starred opposite Kathryn Hahn in Marvel’s “Agatha All Along” on Disney+.
