Continuity mistake: In the scene in the Beatles hotel room where Nancy Allen comes out from under the cart with the cokes on it, when she first sees the Beatles' guitars, notice that in the very first scene, the Hofner bass is left handed (the pick guard is on the left as you're looking at it), then it cuts to her, then when it cuts back to her rolling on the floor with the bass, it's suddenly right handed, then when in the last scene with her handling it, it's left handed again.
Continuity mistake: The Beatles are at the Ed Sullivan Theater rehearsing, yet Nancy Allen is "fondling" Paul's bass and the other instruments back at the hotel. Maybe they're rehearsing a capella.
