Plot hole: At the end of the film, we see Edward carving ice sculptures in his mansion. How did he get the ice up there? First of all, it takes place in a warm climate and I didn't see a freezer up there in the castle. He couldn't have gotten ice from town because firstly he had scissors for hands and couldn't have gripped the ice. And, even if by some miracle he could, he wouldn't be able to buy any from town because everyone in town but Kim was convinced that Edward was dead, she told everyone that they killed each other. And Kim didn't bring it to him because she told her granddaughter in the end that she never saw him again after that night. So where did he get that ice?
Continuity mistake: When Edward pushes Jim out the window, he stabs him in the stomach first. When Jim is backing toward the window, we can see a rip in his shirt where he was stabbed, but when his body is on the ground, there is no rip and the blood is much higher than where he was stabbed.Jennifer 1
Continuity mistake: Edward stabs Jim and crashes him through the large attic window. Eight smaller window sections remain at the top of the opening, two rows of four small windows. All the outside shots (looking up at Edward and Kim) show the two lower left windows broken out, from the inside all eight windows are intact.BocaDavie
Continuity mistake: All thoughout the movie, the scars on Edward's face keep moving and changing sizes and depth.
Revealing mistake: In the scene where Kim comes home early from the camping trip, Edward is startled and begins stabbing the water bed, thus causing it to spring many leaks. If you actually look at the bed, it isn't jiggling like a water bed should and the water is just spraying out even in places he isn't stabbing.
