Harry Trevaldwyn is an author, screenwriter, actor and comedian who in 2022 was listed as a Screen International Star of Tomorrow.

Initially rising to fame through writing and starring in his own online skits, Harry made his screen debut in Netflix’s THE KING opposite Timothée Chalamet, and has since starred in THE BUBBLE and TEN PERCENT (the English language adaptation of CALL MY AGENT). Other credits include SWEET SUE, the comedy series SMOTHERED, indie feature OR SOMETHING LIKE IT, THE OUTLAWS, MY LADY JANE, MY OXFORD YEAR and Tuffnut in the 2025 live-action remake of HOW TO TRAIN YOUR DRAGON.

THE ROMANTIC TRAGEDIES OF A DRAMA KING, Harry’s debut novel, was acquired by Macmillan after a hotly contested 8-publisher auction and published in January 2025 in the UK (First Ink) and US (Wednesday Books). Bursting with hilarious misadventures and queer joy, THE ROMANTIC TRAGEDIES OF A DRAMA KING will be devoured by teenagers and adults who enjoy character-led romantic dilemmas in the tradition of Georgia Nicolson, Lottie Brooks and Bridget Jones. Set against the backdrop of a high school drama production where-of course- the most dramatic events happen off-stage; the story follows loveable Patrick ‘Patch’ Simmons who’s decided that this is the year he gets a boyfriend. Armed with his single mum’s outdated self-help books and an alarming level of self-confidence, Patch embarks on his mission with hilarious results.

As exclusively announced in Variety, THE ROMANTIC TRAGEDIES OF A DRAMA KING has been optioned for TV by producers See-Saw, with Harry adapting the novel himself.

Harry is represented by Isaac Storm at United Agents for his acting and screenwriting.
