Harry Trevaldwyn is an actor, writer and comedian. In 2022, he was listed as a Screen International Star of Tomorrow 2022
He will soon be seen in Universal Pictures’ live action HOW TO TRAIN YOUR DRAGON 2, reprising his supporting lead role of Tuffnut. The first movie was a smash it – topping the US and Global box office.
He also starred in a key supporting role in Netflix feature MY OXFORD YEAR opposite Sofia Carson and Corey Mylchreest. Variety wrote: “Harry Trevaldwyn is a true highlight … His attention-grabbing performance recalls Rhys Ifans in “Notting Hill,” stealing the show as the comedic relief.”
After making his screen debut in a small role in Netflix’s THE KING opposite Timothee Chalamet, Harry went on to play a more significant role in Judd Apatow’s Netflix feature – THE BUBBLE.
He then played the regular role of Ollie in TEN PERCENT, the English language adaptation of CALL MY AGENT, for Amazon Prime Video.
He has also appeared in regular roles in Sky Max’s comedy series – SMOTHERED from Schitt’s Creek writer Monica Heisey, as well as in THE OUTLAWS for BBC One. He featured in recurring roles in Leslye Headland’s STAR WARS series THE ACOLYTE for Disney+ and in Amazon Prime Video’s MY LADY JANE.
Harry received excellent reviews for his co-lead role in indie feature SWEET SUE, with The Arts Desk writing, “Trevaldwyn is a significant discovery” and Screen Daily writing, “Trevaldwyn does a fine job revealing layers under the superficial glitter and fervent self-interest.”
Harry has also had several other nice guest role credits in major series, ranging from I HATE YOU for Channel 4 to the upcoming marquee series, THE THREE BODY PROBLEM, for Netflix. He will also soon be seen opposite Craig Roberts, Julia Davis and Cobie Smulders in Jamie Adam’s semi-improvised indie feature – OR SOMETHING LIKE IT.
After initially rising to fame through writing and starring in his own online skits, Harry’s Channel 4 pilot – BILLI – was released in the spring of 2022. Harry wrote, starred and associate produced. Ben Palmer directed. Big Talk produced with Robert Popper and Caroline Leddy exec producing. Harry was nominated for Best Debut Writer for his work on the pilot at the New Voice Awards 2023.
He has projects in development with numerous leading production companies and has taken part in multiple writers’ rooms for both major domestic and international television projects.
Praise for Harry:
“Trevaldwyn’s sketches are the best thing on the internet.” – Time Out
“Harry Trevaldwyn (there’s at least one breakout in every Apatow movie, and this Instagram impressionist all but steals The Bubble)” – Variety (re Harry’s performance in THE BUBBLE)
“Trevaldwyn provided some much-needed light relief during the UK’s first lockdown . . . he’s been offering up doses of levity ever since.” – The Independent’s 11 comedy stars of the internet to help fight off the January blues
Praise for Harry’s performance in TEN PERCENT:
“All the cast are good, but Steed (as the veteran agent Stella) and Harry Trevaldwyn (as the assistant Ollie) deserve special mentions.” – The Times
“I laughed basically every time Harry Trevaldwyn came on screen as highly strung Ollie.” – The I
“Harry Trevaldwyn stands out as assistant Ollie, always ready with an enthusiastically arch comment.” – Chortle
