Hannah John-Kamen Career
Early Career (2011–2014)
From 2011 through 2014 John-Kamen built a varied resume with television guest roles and theatre work. She appeared in episodes of Misfits, Whitechapel, The Syndicate, The Midnight Beast and The Hour, and secured voice work that linked her to genre productions. Her combination of screen and stage roles during this period showed an early versatility across formats.
The West End run of Viva Forever! ran from December 2012 to June 2013 and gave John-Kamen a lead role in a large-scale commercial musical. While the production received mixed critical response overall, her individual performance drew positive notice and helped broaden her visibility in British theatre and casting circles.
Breakthrough (2015–2018)
John-Kamen’s profile rose significantly after she secured a starring role in the Syfy series Killjoys beginning in 2015. The series offered steady international exposure across multiple seasons and positioned her as a regular in science fiction television, helping to define her early screen persona in genre work.
Between 2016 and 2018 she made several notable television appearances, including a guest role on Game of Thrones and the Black Mirror episode “Playtest.” In film, 2018 marked a major milestone when she portrayed Ava Starr / Ghost in Ant-Man and the Wasp, a supporting but high-profile role in a major Marvel Studios release that brought wider recognition in global film markets.
That same year she also appeared in Ready Player One, where her character was noted for remaining grounded in the film’s real-world sequences even as much of the story unfolded within virtual environments. These film appearances broadened her range from television genre roles to supporting parts in large-scale studio pictures.
Notable Works and Milestones
Across the late 2010s and early 2020s John-Kamen’s credits span television series and feature films. After Killjoys she took roles in Brave New World and the Netflix miniseries The Stranger. Her film credits since Ant-Man and the Wasp include the action-thriller SAS: Red Notice (2021), the Resident Evil reboot Resident Evil: Welcome to Raccoon City (2021) in which she played Jill Valentine, and the 2023 folk horror film Unwelcome.
In 2025 she reprised the role of Ava Starr / Ghost in Thunderbolts* (2025), and it was announced that she would also reprise the role in Avengers: Doomsday (2026). These announcements mark a continuing connection to the Marvel character and to a presence in high-profile franchise filmmaking.
