Quick Reference Facts

Joe Locke was born Joseph William Locke in Douglas, Isle of Man, on 24 September 2003. His mother, Helen Locke, is consistently named across publicly available sources. Information about his father is less clear: some sources refer to him as a businessman named Mr. Locke, while others suggest his identity is not publicly known, and one source mentions a stepfather named Stephen Campbell. Because these accounts conflict, the most reliable conclusion is that his mother is Helen Locke, while his father’s publicly confirmed identity remains unclear. Locke has two older sisters, though they maintain a relatively private profile. He attended Ballakermeen High School and later studied at the University of Chester, though he left formal education to pursue acting full-time.

Locke’s height is commonly listed at 5 ft 9 in (1.75 m), a figure that appears across multiple databases including IMDb and Famous Birthdays. His net worth is a matter of considerable speculation. Estimates range from approximately $600,000 to as high as $5 million, with many sources suggesting a six-figure or low-seven-figure range. However, none of these figures are audited or confirmed by Locke or his representatives, so they should be treated as speculative estimates rather than verified earnings.

What Is Joe Locke Known For? Heartstopper and Breakthrough Role

Joe Locke’s screen breakthrough came in 2022 when he was cast as Charlie Spring in Netflix’s Heartstopper, an adaptation of Alice Oseman’s webcomic and graphic novel. The series follows the romance between Charlie, a quiet and anxious teen who is openly gay, and Nick Nelson, a popular rugby player. Locke’s performance was widely praised for its emotional depth and authenticity, and the show became a cultural phenomenon, particularly among younger audiences.

Heartstopper Season 1 premiered in April 2022 and quickly became one of Netflix’s most-watched original series. Season 2 followed in 2023, and Season 3 aired in 2024. The role made Locke an overnight star and earned him nomination for multiple Rising Star awards. He was also featured on Forbes 30 Under 30 (Europe) in 2025, a recognition that signals his place among the most promising young talents in the industry.

Before his on-screen work, Locke had stage experience. Sources note that he appeared in The Trials in 2022, a play written by Dawn King, which was part of his early career development. He is also described as a model, with magazine appearances including Attitude and Gay Times, reflecting his growing profile in fashion and LGBTQ+ media.

What Marvel Role Is Joe Locke Playing?

Joe Locke plays Billy Kaplan, also known as the Teen, in the 2024 Disney+ series Agatha All Along. This character is a young witch with reality-altering powers who becomes a central figure in the story, and the role has been confirmed by Marvel and Disney official sources.

The casting immediately sparked widespread speculation among Marvel fans because Billy Kaplan is the superhero identity of Wiccan, a prominent member of the Young Avengers in the comics. In the source material, Wiccan is the son of the Scarlet Witch and Vision, and his introduction in Agatha All Along is widely seen as a setup for future MCU storylines. Locke’s casting is therefore significant not just for the role itself, but for what it signals about Marvel’s long-term plans for the Young Avengers narrative within Phase 5 and beyond.

However, while Locke’s appearance as Billy Kaplan in Agatha All Along is confirmed, his future involvement in other MCU projects remains unconfirmed by Marvel or Disney. Industry reports and fan speculation have connected him to potential appearances in Vision Quest or upcoming Avengers films, but as of 2025, no official announcement has been made. The situation is therefore best described as highly anticipated but not yet confirmed.

What Are Joe Locke’s Upcoming Movies and Projects?

Looking ahead, several projects are widely expected for Locke. Heartstopper Season 4 is anticipated for a 2026 release, though Netflix has not yet formally announced the renewal. Given the show’s popularity and the fact that the graphic novel series continues, most observers expect the adaptation to proceed.

In the Marvel sphere, Locke’s future as Wiccan is a major topic of conversation. If the character follows the comic-book trajectory, he could appear in Vision Quest, a Disney+ series centered on Vision, or in the next Avengers films, Kang Dynasty and Secret Wars. These remain speculative at this point, but the foundation has been laid.

Beyond these two major franchises, Locke may also pursue independent film projects. His profile as a rising star with crossover appeal between teen drama and superhero fandoms makes him an attractive prospect for a wide range of productions, though no specific independent projects have been announced as of early 2025.

Does Joe Locke Have Instagram? Social Media Presence

Joe Locke’s Instagram handle is @joelocke03, and he has over 4 million followers as of early 2025. The handle originated when he was younger, with “03” referring to his birth year. His account features a mix of professional announcements, behind-the-scenes photos from Heartstopper and Agatha All Along, and personal posts that give fans a curated view into his life.

Locke has spoken publicly about using Instagram at age 12 to come out as gay to his friends, a post he later deleted after telling his mother privately first. This early experience on the platform shaped his relationship with social media, and he has described his current approach as carefully considered. His Instagram presence is his primary social media channel; he does not maintain a similarly active Twitter or TikTok presence.
