When Eric Draven returns home for the first time after his resurrection the camera pans past the crow. When the crow is out of the frame we hear the sound of its wings fluttering even though the shadow shows the bird is still.
When Skank is in the convenience store to get "smokes and road beers" and sees T-Bird being kidnapped, he limps out of the store _before_ being hit by the car. This is because a scene in which he is shot by someone robbing the store was cut from the final edition. After being hit by a car, the limping is easily explained.
After Skank was hit by the red car he left a large crack in the windshield but at the end of the car chase scene when the police rammed into the red car Skank falls out and the damage to the windshield has disappeared.
When the detective and the cop are arguing about the discovery of a man melted to his blown up car, right after Draven sends the burning car into the river, The detective's shoulder holster changes from brown to black-strapped halfway through the scene.
In the flashback showing how Eric died he's stabbed as soon as he walks in the door, then shot twice (we hear 2 gunshots), and finally thrown backward through a window. As he's putting on his makeup the lightning flashes and 5 bullet wounds can be seen in his back, but moments later when he puts on his shirt there are only 3 holes in his back. When he turns around in addition to the stab wound on the right side of his abdomen there are various other cuts and wounds on his left side. Since he went through the window backward and landed on broken glass the cuts should be on and all over his back (there are none) not on his abdomen (where there are several.)
Black cable visible on and behind white thug falling, by Eric forcing another thugs arm to shoot him 2 or 3 times and falling out window with a tech-9 or mac-10 in his right hand. Scene being reported is just after "Skank" says Jesus Christ and grabs guy to shoot other thug as told above.
After Eric disposes of Funboy he grabs hold of Darla in order to help her see the error of her ways. At one point he holds her, arm extended, and tells her "Morphine is bad for you," whereupon the vein opens and a white fluid drains out. The problem here is that all injectable, liquid oral, and intravenous morphine preparations are a clear light blue in color for safety and identification concerns. The only IV or injectable pharmaceutical that appears milky-white, such as that in the film, is Propofol, an intravenous anesthetic.
