Continuity mistake: The girl dressed in a pastel pink and gold dress, the one that Benvolio likes, is behind him talking in the shot that he's looking out into the dance floor. But in the next shot, the girl comes out from another area, then again in the shot after that, behind Benvolio. (00:23:26)
Continuity mistake: Near the end of the Capulet's party, the revelers form a circle around a minstrel and ask him to sing. Before he begins, he peels off his mask and tosses on the floor. The next shot from a distance shows Juliet running towards the circle, and the minstrel is still wearing his mask. The following shot shows the minstrel up close again with his mask off.
Continuity mistake: At Juliet's funeral, a group of maidens step forward and toss roses onto her body before she is placed in the tomb. The scene changes to a more distant shot showing one maiden from the original group in a different location tossing more roses which land on Olivia Hussey's face. Did she forget to toss all her roses the first time?
Audio problem: The choirboys sing throughout Juliet's funeral. There are also four flute players standing on a rise over her body at the tomb's entrance. However, no notes can be heard from any instrument even though they all give the appearance of playing. In a subsequent shot, one of the musicians does not even have his instrument up to his mouth while another one stops playing before the scene ends and is just standing there.
Continuity mistake: As Juliet is telling Nurse to go tell her Mother that she has gone to Friar Lawrence's call to make confession, her hair is draped over her left shoulder as seen from the front. With an immediate cut from behind, her hair is fully over her back when she turns round to look at Nurse.
