Here's everyone who stars in The Irregulars cast and where viewers might have seen them before. The Irregulars features Sir Arthur Conan Doyle's famous novel characters Sherlock Holmes and Dr. Watson, but updates the storyline for a modern audience, and with a supernatural twist. The Irregulars tells a slightly-familiar tale involving and includes familiar faces from TV, but its young cast of rising stars are the main protagonists.
Set in Victorian London, The Irregulars follows a group of Baker Street orphans. When a mysterious gentleman named Mr. Watson makes a business proposition to the title characters, it leads to the revelation that one of them has metaphysical abilities. The Irregulars initially teases the whereabouts of Sherlock Holmes, who eventually becomes a more prominent figure when local baddies open up a new realm. The Netflix series follows the street orphans as they investigate bizarres crimes within their community, and thematically complements the 2020 release of Enola Holmes.
The Irregulars cast includes two British actors as Sherlock Holmes and Dr. Watson, while the rest of the lineup spotlights numerous teenage and young adult performers. Overall, the series is indeed geared towards a millennial audience, which may at once feel jarring and perhaps refreshing when considering the subplot involving two iconic literary characters.
