What Are Joe Locke’s Best Movies and TV Shows?
Locke’s screen credits are compact but high-profile. Two television roles define most of his public career so far: Charlie Spring in Heartstopper and Billy Maximoff in Agatha All Along. His stage credits add a separate layer to that résumé.
Heartstopper (2022–2024): The Role That Made Him Famous
Netflix’s Heartstopper ran for three seasons and was adapted from Alice Oseman’s webcomic and graphic novel series. Locke played Charlie Spring, one of the two leads, and received Children’s and Family Emmy Award nominations for the performance. He won on his second nomination in 2025.
In April 2025, Netflix announced a finale film, Heartstopper Forever, to close out the story. For a complete rundown of the actors involved, the Heartstopper cast Netflix guide covers the main ensemble.
Agatha All Along (2024): Billy Maximoff and the Marvel Connection
Locke was announced for Marvel Studios’ Disney+ series Agatha All Along in November 2022. The show premiered in 2024, with Locke playing the character known at first only as Teen. Different sources later identify the role as Billy Maximoff or William Kaplan, the Marvel Comics character also connected to the name Wiccan.
TV Insider’s profile lists him in the role under multiple names, reflecting how different parts of the franchise and its databases describe the same character.
Sources describe the role in different ways. Some list him simply as Teen, while others name the character Billy Maximoff or William Kaplan. The different labels come from different points in the story and different databases, so none of them is incorrect on its own; they all refer to the same character in Agatha All Along.
Stage Work: From Donmar Warehouse to Broadway
Locke’s professional stage debut came in 2022 in The Trials at Donmar Warehouse in London. The Broadway.com profile notes the debut and the professional debut award that followed.
In 2024, he made his Broadway debut as Tobias Ragg in Sweeney Todd: The Demon Barber of Fleet Street, a production referenced in his All American Speakers profile and on The Movie Database.
