Continuity mistake: Between the first and second song by Katie, she turns towards Angie and Luke. Continuity errors happen there, with her doing twice the gesture to open quizzically the arms she was clutching the microphone with, to the mic itself suddenly switching hand, from left to right. (01:17:10)
Continuity mistake: Katie does her second performance, the song "Bless myself." Her friend comes onstage to help her out of the leather jacket. In the next wider shot, both girls are pulling at the same jacket between them...but Angie was already wearing a black jacket herself, and now she is not. (01:17:30)
Continuity mistake: When Angie rushes to hug Katie from behind after hearing the evil stepmom's threats backstage, Lucy Hale's hair is parted differently between shots (she has more or less hair in front of either shoulders, and it keeps switching). (01:11:05)
Continuity mistake: Katie tells Victor that she sorta loves him; Meatball has his hand on Victor's shoulder all of a sudden. His hands also assume inconsistent positions when he keeps getting cut off by Katie a few seconds later, being open or pointing fingers. (01:06:10)
Continuity mistake: Talking about the musical qualities of rosewood, Luke holds the guitar with an upward hand, downward in the shots that follow and precede. There are other continuity mistakes in the scene, including a very noticeable one when Victor runs off and when Luke comments on the missing head of the painting; all of a sudden he's not holding the guitar at all. (00:56:10 - 00:56:50)
Continuity mistake: At the end of the little practice session with Victor, Luke tells him he could be a Beatle. Victor's hand goes from the bottom of the guitar to his mouth - it's not even the first time it happens in the scene, the takes from behind the child actor have choppy continuity. (00:55:00 - 00:56:00)
Continuity mistake: Throughout dinner, Bev's steak and lettuce keep changing place randomly. Moreso, when she takes a break she puts the napkin on top of the food, but when she is back, the napkin is at the side of the plate. Between shots the cloth also ends up crumpled differently. (00:50:00 - 00:54:00)
Continuity mistake: Luke invited Bev to dinner. Walking back from the car, Gail tells Katie to write a song for her daughter. There's an obvious cut during their walk, and in that cut it's easy to tell how the extras walking on the opposite sidewalk disappeared, while a new one appeared. (00:49:20)
Continuity mistake: Angie takes off her veil during the dance-off with the principal; when the two are dancing aligned belly to back, in the crowd behind Gail on the left of the screen there are two girls, one in pink and one in orange. They are side by side in the closer shots, but there are guys between them in the wider angles. It keeps switching back and forth. (00:39:50)
Continuity mistake: When Gail approaches Bev at the Bollywood event, behind them there's a juggler, who disappears at the cut. (00:36:25)
Character mistake: Gail reads right through Katie's poor excuse about crotcheting, and says she won't go to the ball "after what you pulled today with Guy." She did not do it (well she didn't do anything, but 'supposedly did') today, but yesterday. (00:31:00)
Continuity mistake: Talking about plans for the ball, Angie takes a bite of the sandwich. Cut for a few moments on Katie, and Angie is now also holding a big mug. So far it's not quite practical but technically possible. But after a couple more cuts, Angie's sandwich is now half-eaten, way too fast. (00:30:10)
Continuity mistake: After shooing Luke, Gail tells Bev that she'll lip sync to Katie. She has her hand on her shoulder, but pulls the arm back before the cut. Next shot and her hand is back on her daughter's shoulder. Same thing happens a bit later during the Colin Farrell peen joke. (00:22:55)
Continuity mistake: Luke is talking with Mickey O'Malley the day after the first meeting with Bev and Katie. The unlikely Irish names some fictional group called "Oral Majority." A guy in an indigo shirt walks past them, moving in the opposite direction. Next shot, the same guy crosses the street in front of them. The same guy pops into shot 'just passing by' another 3-4 times. (00:24:30)
Plot hole: Gail and Katie talk in her shed about Guy's phone call. Katie says "I didn't lie about anything", which is a really odd non sequitur. All Gail said was "I just got off the phone with Guy Morgan. Your phone. He just loved that little demo you left him. I have underestimated you. It'd make me proud if I actually cared about you." Nothing about it prompts a response like that, except the plot point that Gail told Guy that Katie lied about it appropriating Bev's demo. But Katie does not know that fact at that point. (00:21:00)
Revealing mistake: When Victor pulls the towel off Katie, she ends up facing him, and then instead of resisting, holding the towel or shoving him off (he's a kid, she towers over him) she blatantly spins away to be stripped and literally walks off the door so he can lock her out. Can't get much more obvious than that. (00:16:20)
Continuity mistake: Gail tells her daughter she wants to be 6'4" and puts her chin on top of her hands. Her left hand is on top of the right. Except, in the next shot it's the opposite. Back to left-right when we're back on the previous angle. (00:14:10)
Continuity mistake: At dinner, once Gail uses the "Make me one with everything" line, Katie is moving around the table to get seated. Victor is drinking, but after the cut he's eating with a fork. Gail is about to talk about her big break, her hand is down, and then up after the cut. (00:12:25)
Continuity mistake: In the Dean's office, Luke sighs when his dad talks about the distinction between musicians and businessmen, and brings his hand to his temple. Camera back on Guy, and Luke's hand is not there. Moreover, a couple seconds later Katie comes running, and a new inconsistency appears; Luke's arm is on the armrest, but in the pensive/malincholic position again in the wider shot. (00:05:10)
Continuity mistake: Katie slaps away Victor's handful of earthworms, but they get inside the blender. In the close-up you can see a few worms miss the open blender and fall to the side, on the counter. When Gail arrives, those telltale protostomes have disappeared. (00:03:20)
