Plot holes: Powder is supposedly unable to grow hair, yet throughout the entire movie he has eyelashes.
Continuity: When the girl is lying on the bed, the lamp changes sides between shots.
Continuity: When Powder gets his first kiss with the redhead, you see her standing when her father is coming towards them, but then in the next shot she's still sitting and just about to get up.
Miscellaneous: In the final confrontation with John, the button on his jeans are magnetically drawn to Jeremy, but the identical buttons on his denim jacket are somehow unaffected.
Continuity: Again, in the final confrontation with John, the button on his jeans are magnetically drawn to Jeremy and pop open, but when you see him on the floor following the electric shock, they're still done up.
Factual errors: After the deer is shot by the hunter, within seconds of dying the animals legs appear stiff and suspended in mid-air. Rigamortis does not set in this quickly. The deers limbs should have remained limp.
Errors made by characters (possibly deliberate errors by the filmmakers): During one scene at a park bench we can see Powder's left hand under the table which appears normal, while his right hand and the rest of his body appears to be that of an albino.
