What's left of the old woman's house after it's burned down is represented by a few pieces of completely unburned wood with no other derbies (I.E: ash or burned wood) visible.
When the Judge confronts Pumpkinhead, he pulls a revolver and fires. Though the revolver is a six shooter, the gun actually fires eight rounds continuously without reloading.
When Danny fires a pistol at Pumpkinhead, he fires 9 rounds. The pistol that he fired is a Colt M1911 pistol which can hold but 8 rounds, 7 in the magazine and one in the firing chamber.
When Pumpkinhead bursts into the Judge's house, you can see the tennis shoes the actor of Pumpkinhead is wearing. (FULLSCREEN ONLY).
At the end of the movie, when Pumpkinhead is hanging over the mine from the hook, you can see lines attached to both of his arms so someone can puppet them on either side.
Safety line visible several times when Danny swings across the mine on the hook.
