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: During the "Lake Minnetonka" scene, Prince's motorcycle tire automagically changes from knobby to street and back. (00:21:54)
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. (00:15:42)
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. (00:47:39)
