Felix Leech is a British stunt performer, officially recognised since April 2014 as a qualified member of the British Stunt Register and an Equity Union member. He stands at 6′1″ with brown hair and eyes, an athletic build, and dual British and Australian citizenship. With fluency in languages such as Japanese, French, and Korean and a background that includes qualifications like PADI Divemaster certification, Leech brings a broad skill set to his stunts—ranging from boxing and karate to high falls, wire work, and creature contortion.

Leech has earned acclaim as a stunt double for a variety of leading actors, often specialising in younger or thinner character types due to his physical versatility. His on-screen and stunt credits include major Hollywood blockbusters like The Batman, Star Wars: The Rise of Skywalker, Eternals, Andor, Ant-Man and the Wasp: Quantumania, and Paddington 2. Notably, he doubled for actors including Hugh Bonneville (Paddington 2), Asa Butterfield (Sex Education) and Benedict Cumberbatch (Brexit), among others.

Leech is also highly adept at creature performance and contortion. His broad professional range is further evidenced by his work in television series like Game of Thrones, Sex Education, Gangs of London, Stath Lets Flats, Coronation Street, and The ABC Murders.
