Guy Trevellyan is a British writer, director, and producer whose work fuses environmental and psychological themes into bold, genre-defying storytelling. Blending drama, thriller, fantasy, and horror, crafting character-driven narratives that tackle complex social and human issues.

He gained international recognition with his 2025 short film Plastic Surgery, which won Best Thriller at the Academy Award qualifying HollyShorts Film Festival and Best Narrative Short (Horror, Sci-Fi, Thriller) at Cinequest Film Festival, among other accolades.

Since graduating from the MetFilm School, Trevellyan has honed a distinctive visual and narrative style while working as an Assistant Director alongside filmmakers such as Wes Anderson, Greta Gerwig, Michael Sarnoski, Sam Esmail, and Danny Boyle among others. These collaborations significantly shaped his approach to both storytelling and cinematic craft.

In 2024, he founded Nice Guy Pictures, a production company dedicated to creating visually compelling stories with deeper thematic resonance, often exploring personal vulnerability and urgent global issues such as climate change and plastic pollution.

His upcoming charity-backed project, The Act of Learning, draws on his own experiences to explore the realities of undiagnosed dyslexia growing up.
