Jamie Demetriou is best known for playing the titular incompetent letting agent in "Stath Lets Flats", a show which he also wrote. He has also guest starred in other comedy series including "Fleabag", "Miracle Workers", and "The Great". He recently was also part of the main cast of "The Afterparty", an AppleTV+ murder mystery comedy, created by Lord and Miller ("21 Jump Street", "The Lego Movie").
He is no stranger to film either, having starred in "Paddington 2", "Horrible Histories: The Movie", and "Cruella", among a number of other titles.
In the "Barbie" universe, he doesn't quite have Ken-ergy, and will instead be playing one of the Mattel employees that Barbie encounters in the real world. As his character poster sums up: "he's a suit".
