Continuity mistake: Maddie and Taylor are talking about Maddie being over her previous fiance (that Taylor knows of). Taylor has the hair on her right side tucked into her jacket, but next time the camera is on her, her hair is neatly arranged over the shoulder. Similarly, her hair on the left shoulder changes position between shots just before Maddie drags her out to meet their plus-size friend. (00:06:20)
Continuity mistake: In the scene where Tommy is arguing with Bob Crewe after the song "Trance", Tommy puts his arm up on the music stand while he argues. In the next shot Tommy's arms are now at his side. When the camera comes back to Tommy, his arm is on the music stand again. (00:49:50)
