Continuity mistake: There wasn't much blood noticeable on the axe after it was used to chop off the mermaid's tail, but a little later when the man was carrying it over his shoulder, it was heavily covered in blood and dripping. (00:14:17)
Continuity mistake: The distance between Dr. Beyer's car waiting on the road and the mermaid/wheelchair crossing in front varies (some shots being closer). Also, after the doctor hit the mermaid/wheelchair and stopped near the parked white car, the red truck should still be visible. (01:02:58)
