Guy Trevellyan is a British writer, director, and producer known for bold, genre‑defying storytelling that fuses environmental urgency with psychological depth. Working across drama, thriller, fantasy, and horror, his films are deeply character‑driven and challenge audiences to confront complex social and human issues.

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

Since graduating from MetFilm School, Trevellyan has developed a distinctive visual and narrative voice while working as an Assistant Director alongside filmmakers including Wes Anderson, Greta Gerwig, Michael Sarnoski, Sam Esmail, and Danny Boyle. These collaborations have played a key role in shaping his cinematic craft.

In 2024, he founded Nice Guy Pictures, a production company dedicated to visually striking stories with deeper thematic resonance—often exploring personal vulnerability alongside 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 growing up with undiagnosed dyslexia, continuing his commitment to socially engaged, emotionally grounded storytelling.
