Factual error: The movie starts with "cawing" from a Crow, but shows a Raven perching on a rail. A Raven is easily distinguishable from a Crow by the curve/hook at the end of its beak, which was present. (00:00:13 - 00:00:39)
Continuity mistake: The length of the pole the scarecrow was on varied between close-ups of his face (where the pole did not extend above his head) and wider views (where the pole extended 3-4" above his head). (00:24:40 - 00:25:05)
