Continuity mistake: All thoughout the movie, the scars on Edward's face keep moving and changing sizes and depth.
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: 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: Many of the bush sculptures that Edward creates in the neighborhood are significantly taller than the original shrubberies.
