Osterfield, who rounds out the Irregulars group as Leopold, is a model-turned-actor with an unexpected link to one of the world's biggest movie franchises. After working as Tom Holland's personal assistant, Osterfield got uncredited cameos as a student in both Spider-Man: Homecoming and Avengers: Infinity War. He also had a minor role in the Hulu miniseries adaptation of Catch-22 airing in the US.

Henry Lloyd-Hughes as Sherlock Holmes

Lloyd-Huges is taking on the iconic role of Sherlock Holmes, so it seems fitting that he got his first movie role in an iconic franchise too. He appeared in the minor role of Hogwarts student Roger Davies in Harry Potter and the Goblet of Fire back in 2005, and since then, he's been working steadily in both television and major motion pictures. His movie credits include Anna Karenina, Madame Bovary, and Now You See Me 2, while his TV resume includes historical dramas like Les Miserables and Indian Summers. Most recently, he played Aaron Peel on the second season of Killing Eve.

Pierreson is set to play a new, darker version of Dr. Watson. So far, he's built a steady career alternating between TV and movies, including roles on both Death in Paradise and Line of Duty. He also appeared in Netflix's The Witcher as Istredd, and he has something in common with one of his co-stars: like Darci Shaw, he had a role in the film Judy.

Clarke Peters as The Linen Man

Peters, whose character has the eerie and intriguing name "The Linen Man," is something of a TV drama staple. He's worked with David Simon on acclaimed HBO dramas twice, playing detective Lester Freamon on The Wire and Albert "Big Chief" Lambreaux on Treme. You also may recognise him from playing the Master of Jordan College in season one of His Dark Materials. Peters also has worked in some top-notch films over his decades-long career; recent credits include Three Billboards Outside Ebbing, Missouri and Da 5 Bloods
