Continuity: Stuart Sutcliffe talks in a Liverpool accent throughout the film.  However, unlike the other Beatles, Sutcliffe didn't have a Liverpool accent.  He was born in Scotland and raised in Lancaster.  He didn't come to Liverpool until he was 16.

Continuity: Near the end Stuart opens a package containing the Beatles' first single. When it shows a close up of the record you see a cigarette in his right hand, but when it cuts back to the shot of Stuart he doesn't have a cigarette.

Continuity: In the scene where Astrid tells John at the airport that Stuart is dead he cries and hugs her. In reality he began to burst into laughter . Astrid herself said: "He never cried. Not once. He went into this hysterical laughter and couldn't stop. It was his way of not wanting to face the truth."  (Lennon- The Definitive Biography, by Ray Coleman).

Factual error: In the film, John Lennon sings "Long Tall Sally" when it was actually Paul McCartney who sang/recorded the song.
