The series will touchdown on Netflix on March 26th, 2021.

Netflix officially unveiled the show in late February 2021 where it released some first look pictures and its first teaser trailer (more promotion expected throughout March 2021).

Bidwell commented on working on The Irregulars in a BBC interview:

“It’s my dream project and my oldest idea (I’ve been pitching it for ten years) and I couldn’t be more thrilled to be working on it with the team I made My Mad Fat Diary with at Drama Republic. Netflix are incredibly supportive for our vision for the show and it’s allowing us to be very ambitious with the way we’re telling our stories.”

What is the plot of The Irregulars?

Not very much is known about the plot since this is only an original work based on Arthur Conan Doyle’s characters. Very much like the Enola Holmes book series by Nancy Springer which was adapted into a Netflix film starring Millie Bobbie Brown (Stranger Things) and Henry Cavill (The Witcher).

The synopsis for The Irregulars reads:

“Set in Victorian London, The Irregulars follows a gang of troubled delinquent teens who are manipulated into solving crimes for the sinister Doctor Watson and his mysterious business partner. As the crimes take on a horrifying supernatural edge and a dark power emerges, it’ll be up to the Irregulars to come together to save London, each other, and potentially the entire world.”
