John-Kamen started as a voice actor for Dark Souls, a video game published in 2011. By 2011, she began to appear and land roles in television series like Whitechapel, The Midnight Beast, The Syndicate, and The Hour. The sexy starlet proves her versatility in acting by landing on a lead role for a Spice Girls-themed musical. Unfortunately, after the premiere in Piccadilly Theatre, the musical received negative feedbacks. Only The Daily Mirror published a review of praise for John-Kamen’s performance.
The English actress appeared on the music video of The Chemical Brothers’ Sometimes I Feel So Deserted and Sun Silva’s Just the Romantic.
Making her way in blockbuster films, the actress scores a role in Steven Spielberg’s science fiction film, Ready Player One. John-Kamen received another positive criticism regarding her role in the movie. Playing a role in the movie was a dream come true for Hannah, who grew up engaged in cult classics and American pop culture. Her character was a leader of the antagonist group, set out to cheat to win the game.
2018 brought Hannah massive projects. She joined the casts of Tomb Raider. John-Kamen was to portray Sophie, a significant supporting role. Despite the film and its production team berated and cursed for their casting decisions, John-Kamen as Sophie was fan-approved. Fan edits spread through the internet to visualize and even compare how John-Kamen’s fit sexy body fits into the physique of the character. Another project she successfully worked on in the same year was, Ant-Man and the Wasp. Her character Ava Starr also known as Ghost, a kick-ass supervillain in the film. Fortunately, her portrayal was well-received by avid Marvel fans and critics. With her astounding performance and given justice to the role of a supervillain, fans want her back on the next Ant-Man movie franchise.
Fans have always loved John-Kame. Starting as the show’s main lead as Dutch/ Aneela in the science fiction series, Killjoys, her performance received praise. From portraying a hot bounty hunter to a completely different person in the same scene. The actress always handled her intimate scenes professionally, but she never shied away from bikini scenes. The actress shared how she was comfortable with her body.
