Continuity: A scene dated March 1961 has George being wished a happy 18th birthday. George's actual birthday was in February (as was even mentioned earlier in the film.)
Miscellaneous: At the end of the film, text describing subsequent events is superimposed over shots of a beach. One paragraph notes that Klaus Voormann played bass on John Lennon's album "Imagine" and designed the Beatles' "Revolver" album cover, but although the former title is placed in quotation marks, the latter is not.
