Continuity mistake: When the woman confronts Morris and Jerome on the street about how long she waited the night before for Morris, she first appears without an over the shoulder pocketbook. The camera angle changes and you can see the strap on her shoulder. The camera angle changes again and the strap is gone.
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.
Visible crew/equipment: When Morris turns to face the mirror to see what the suit that he is holding will look like pressed against him, as soon as he turns and faces the mirror, look at the right side of the mirror where the edge of the open door is, you can see a crew member with the white baseball cap ducking behind the door trying to stay out of the shot.
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.
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.
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.
Continuity mistake: While enroute to the 'Lake Minnetonka' scene, Prince, or his stunt double, is seen from the helicopter cam as wearing the purple coat. As the truck cams show Prince and Apollonia on the bike, he's wearing the black coat. This is best seen after Prince passes the horses.
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.
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.
