Continuity mistake: When The Kid is at home he puts Wendy and Lisa's tape in his player and you see him put the tape holder on the player in front of the small lamp. The camera angle changes to a close up and the tape holder is now on the side on the lamp which has moved to allow the holder to be on the side. (00:47:39)
Continuity mistake: The Kid receives a white guitar from Appolonia placing it in his lap. They kiss. His arms are still placed on the guitar. She tells him that she is going to join Morris's group. As he jumps up and slaps her in the face, the guitar is gone. (00:48:50)
Continuity mistake: When Apollonia tells The Kid that she is going to join Morris' group, he slaps her and makes her fall into the dresser where you see what looks like a red shirt hanging from the top of the second draw down the length of the dresser. The camera angle changes and the shirt is now seen much shorter in length. (00:51:52)
Continuity mistake: When Morris and Apollonia are in the car in front of the club, you can hear them talking, but when Morris says something to Jerome, Morris' lips move but you can't hear him. (01:03:37)
Continuity mistake: After Jerome scolds The Kid about Darling Nikki and throws him tickets to Apollonia 6 show, he walks past the doorway. The camera frame jumps slightly up before he pops his head in to deliver the line, "Don't forget to bring a girlfriend." It's appears they had several takes of him popping back into frame, but didn't lock down the camera so, it doesn't match. (01:06:44)
Continuity mistake: After The Kid runs off the stage while singing "Darling Nikki" he is seen in his dressing room with sweat on his back and chest. When the club owner goes in to yell at him for leaving the stage, he is now completely dry. (01:07:48)
Continuity mistake: When The Kid knocks Morris into the pile of boxes in the alley, you can see that the stunt double taking the fall is white, and when he lands in the pile of boxes he is seen in the next camera angle laying on a different set of boxes. (01:14:11)
Continuity mistake: Right after The Kid rescues Apollonia from Morris in the alley, he drives her to a secluded area where the makeup on her face is now brighter and heavier than it was in the alley. (01:15:42)
Factual error: Right after The Kid's father shoots himself, The Kid is seen in the basement being interviewed by two police officers in uniform and one detective. One of the police officers is asking the questions while the detective is writing in his notepad. Standard procedure is for a "Lead Detective" to be assigned to the case and he conducts all interviews. (01:18:49)
Continuity mistake: Right after The Kid sees an image of himself hanging in the basement, he grabs a stick and starts smashing food jars on a shelf. The camera angle changes and he's seen smashing the same jars again. (01:19:54)
Continuity mistake: When The Kid starts smashing the food jars in the basement with a stick, he starts with the first shelf and then he smashes the jars on the 2nd shelf and then there is a close up of him smashing more jars on yet another shelf. (The jars are different). When the camera angle changes to a wide-shot, none of the jars on the 2nd shelf are damaged, and where did the third shelf come from? He is then seen smashing the jars on the 2nd shelf again. (01:19:58)
Continuity mistake: When The Kid goes home and sees his mother's crying in the front yard it is daytime. He immediately goes inside to confront his dad and the windows show that it is now night.
Other mistake: When Apollonia is smacked in the face by the Kid after announcing she's joining Morris's group, she falls into a dresser and knocks all the magazines off the top of the dresser on to the floor. When the same scene is replayed during the 'When Doves Cry' sequence, the magazines don't fall to the floor.
Continuity mistake: In the scene where The Kid "flips-out" and destroys his basement with a stick, he deliberately breaks several mason jars of preserves that are sitting on two adjacent bookshelves. Near the end of that scene just before he finds his father's music sheets, you can see that the same jars he just exploded all over the basement are now back on the bookshelf perfectly intact.
Deliberate mistake: Before going on stage in the infamous purple coat for the first time in the movie, the Kid is in his dressing room. The silver jewelry/decoration on his coat is on the left shoulder. In all subsequent shots, the silver jewelry/decoration is on his right shoulder.
Audio problem: When Jerome and Morris are walking around the block, discussing the problems with the girls' group, Morris says "That Apollonia babe we saw last night," and his lips don't move in sync with the dialogue. He's actually mouthing "Vanity" instead of "Apollonia", indicating that the scene was filmed before Vanity backed out of the shoot.
