Factual error: In the scene where Robert Duvall, Michael Caine and Haley Joel Osment are in a general store/coffee shop and the young punks come in, there is a Coca-Cola machine shown that has the "Wave" logo and a slogan that was used in the 1970s, not in the time period in which the movie took place (1950s/60s).
Continuity mistake: When the lion cage is standing in the yard, sunlight and shade keeps changing. First the cage is fully in the shade, but when the uncles approach the sun is shining on it. When the cage is open, the light on Garth and on the lion's fur comes from opposite directions. After the cage is closed it's back in the shade again.
Continuity mistake: When Walter's mother last drives off, all the dogs jump at Walter's window, then sit right next to the car. When the car pulls away however, the dogs are a few feet back and not in a line, but when the camera cuts back to the dogs, they are where they were to begin with.
Continuity mistake: When Walter opens the chest its contents are covered by a smooth layer of sand. When he reaches in in the next shot there are already tracks made by his fingers. Then he removes the sand from Jasmine's photograph that we can see her face, but in the next shot the face is mostly covered again.
Continuity mistake: Before Walter's mother drives off she asks Walter to give her a big smile. While he is trying very hard the camera cuts back and forth between him and his mom. When the camera is on him a rather strong wind moves his collar and his hair, and when it's on her there's no wind at all.
