Acting
Harry Trevaldwyn is an actor, writer and comedian. In 2022, he was listed as a Screen International Star of Tomorrow 2022
He can be seen in a supporting role in the Universal Pictures' live action HOW TO TRAIN YOUR DRAGON which topped the US and Global box office.
He can also recently be seen in a supporting role in Netflix feature MY OXFORD YEAR opposite Sofia Carson and Corey Mylchreest. With this role he “steals scenes (and hearts)”.
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 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:
Time Out - "Trevaldwyn's sketches are the best thing on the internet."
I Talk Telly recently named Harry as one of their "22 TV Stars of Tomorrow for 2022"
Variety (re Harry's performance in THE BUBBLE) - "Harry Trevaldwyn (there’s at least one breakout in every Apatow movie, and this Instagram impressionist all but steals The Bubble)"
The Independent's 11 comedy stars of the internet to help fight off the January blues - "Trevaldwyn provided some much-needed light relief during the UK's first lockdown . . . he's been offering up doses of levity ever since."
The Times' 10 comedy acts who went big on social media - "There are a ton of comics having fun online messing with middle-class mores, but nodody does it with more finesse than the lean and gently lacerating Trevaldwyn."
David Walliams - "One of the most original and funniest writer-performers working today. Harry is going to be a huge star. The writing is flawless."
Praise for Harry’s performance in TEN PERCENT:
The Times - “All the cast are good, but Steed (as the veteran agent Stella) and Harry Trevaldwyn (as the assistant Ollie) deserve special mentions.”
The I - “I laughed basically every time Harry Trevaldwyn came on screen as highly strung Ollie.”
Chortle - “Harry Trevaldwyn stands out as assistant Ollie, always ready with an enthusiastically arch comment.”
