Continuity mistake: As the boys leave in the helicopter at the end of the film, it says "BEATLES" on the aircraft's door. The name is split into two different sections to fit on the sliding panels. A few seconds later, one half of the name is missing, leaving only "BEA" on the left-hand side.
Continuity mistake: As he talks to Norm, Shake the TV producer says, " If they don't show up I wouldn't be in your shoes for all the tea in China" and the clock above his head reads 7:12 PM. In the next shot we see Paul's grandfather trying to sell autographed pictures of The Beatles to the girls on line outside the theater and it's mid-afternoon. (01:05:25)
Continuity mistake: Wilfrid Brambell asks Paul to sign a Beatle picture and he uses a ballpoint pen. Later, he copies them over using the master copy that The Beatles signed with ballpoint pens. Their signatures are now different (done with a thick felt marker) so they can stand out better in the black and white shot. (00:09:10 - 00:45:50)
Continuity mistake: Upon their return the TV producer says to The Beatles, " You don't know what this means to me, if you hadn't come back it would have meant The Epilogue or News in Welsh" as they get ready for the show. Norm is standing behind the producer but then in the next shot as he talks to him he's on his right. (01:14:00)
