Asa Butterfield, Jonny Lee Miller and Christine Tremarco have joined the cast of drama series “Hamburg Days,” about the Beatles’ formative years in the German port city.

The six-part show, which was created by showrunner Christian Schwochow (“The Crown,” “Munich – The Edge of War”) and head writer Jamie Carragher (“Succession”), is shooting in Hamburg. It is inspired by German artist Klaus Voormann’s autobiography.

Butterfield (“Sex Education,” “Unchosen”) will play Beatles manager Brian Epstein, while Lee Miller (“Trainspotting,” “The Crown”) takes the role of Jim McCartney, the father of Paul McCartney. Also joining the series are Tremarco (“Adolescence,” “The Responder”) as John Lennon’s guardian Aunt Mimi, Darci Shaw (“A Thousand Blows,” “This City Is Ours”) as Cynthia Lennon, Ryan Sampson (“Mr Bigstuff,” “Brassic”) as Liverpool promoter Alan Williams, Archie George as singer Tony Sheridan, Jorden Myrie (“Sherwood,” “The Strays”) as Lord Woodbine, Lea Drinda (“The Sound of Falling,” “Where’s Wanda?”) as Astrid Kirchherr, Tash Major (“Finding Emily,” “Saviour”) as Dot Rhone, and Louis McCartney (“Stranger Things: The First Shadow”), who will play Ringo Starr.

They join the previously announced cast including Rhys Mannion as John Lennon, Ellis Murphy as Paul McCartney, Harvey Brett as George Harrison, Louis Landau as Stu Sutcliffe, Patrick Gilmore as Pete Best, and Casper von Bülow as Voormann.

“Hamburg Days” is set in the early 1960s in the smoke-filled clubs of Hamburg’s St. Pauli red-light district, where an inexperienced young rock ’n’ roll band from Liverpool collides with two young artists, Voormann and Kirchherr. Together they help spark a transformation that turns a scrappy group of teenagers into the greatest music phenomenon the world has ever known.

AGC International is handling worldwide sales outside the U.K., where the BBC has the rights, and Germany, where ZDF will screen the series.

W&B Television and Turbine Studios are producing the show, with music curated by David Holmes (“Killing Eve,” “Ocean’s” franchise).

“Hamburg Days” was developed by Benjamin Benedict (“Generation War”) and is written by Carragher, who also serves as executive producer. Showrunner and executive producer Schwochow is directing alongside Laura Lackmann (“Call My Agent Berlin,” “The Pimp: No F***ing Fairytale”). Frank Lamm (“Andor,” “The Crown”) serves as director of photography. Voormann is an exclusive consultant to the series.

Executive producers are Benedict, Quirin Berg and Max Wiedemann of W&B Television, Andrew Eaton and Justin Thomson of Turbine Studios, and AGC’s Stuart Ford, Lourdes Diaz and Miguel A. Palos Jr., Isabel Haug and Charles Breitkreuz for W&B Television and Katharina Haase serve as producers. At ZDF, the project is overseen by Alexandra Staib, Caroline von Senden and Sandra Dettki.

“Hamburg Days” is being produced with the support of the German Motion Picture Fund (GMPF), MOIN Filmförderung Hamburg Schleswig-Holstein, FilmFernsehFonds Bayern and Medienboard Berlin Brandenburg.

The series will film in Hamburg, Munich and Liverpool.
