Hamburg Days started production in Germany and Liverpool in May.
The Beatles performed more than 250 gigs in the German port city between 1960 and 1962.
The series has been inspired by the memoirs of Klaus Voormann, who met the band in Hamburg as a young artist and went on to design the cover of their Revolver album in 1966 before later appearing on John Lennon, Ringo Starr and George Harrison’s solo albums.
Producers said the series would show the band – which at the time included bassist Stuart Sutcliffe and drummer Pete Best – meeting Voorman and photographer Astrid Kirchherr.
The drama has been scripted by Wirral-born Jamie Carragher – one of the writers behind the HBO comedy-drama Succession.
Director Christian Schwochow, who worked on the Netflix series The Crown, is the showrunner of the series, and Bafta-winner David Holmes, who worked on Killing Eve and the Ocean’s franchise, will curate the music.
