During Hub's fight with the teens, no one lays a hand, or knife on him. At the end it can be clearly seen that Hub's shirt is whole. When they get back to the farm, he has several small knife holes in the upper left.
While Hub is fighting the teens in the diner there is a coke machine in the background with the modern logo on it (should be all red with white Coca Cola lettering). Also visible is the pinball machine Odds & Evens which dates to 1973.
At the beginning of the movie, Hub and Garth are flying in their biplane. They fly past a police cruiser, in which the cop is sleeping. A view of the rearview mirror shows that the cop is already awake, but a second later we see him suddenly wake up.
In the bar fight the shotgun is cycled open and closed to chamber a shell and get attention. In following camera shot action is open (wooden forearm to rear of barrel). For remaining scenes the action is again closed (wooden forearm back to front of barrel).
In the beginning when Walter comes across Jasmine's photo, he opens the trunk and we see mostly smooth sand. However, in the next shot where he is reaching down into the trunk, we see that a hand has already disturbed the sand.
When the lion is in the crate and they are going to shoot it you can see the chain holding the lion in the crate running down her chest partly exposed, they tried covering it up with fur, you can see it in several shots.
Hub refers to lions as living in the jungle. Even though this is technically incorrect as they live in the Savanna, not the jungle, it is an understandable error because lions are commonly referred to as the "King of the Jungle".
The front porch of the house changes from scene to scene in the beginning. Initially the porch is all screened-in. The next shot has the screens at the back of the open porch. The next shot has the porch built out. But most of the time, the porch has the screens at the back of the squared off porch.
The goof items below may give away important plot points.
At the end of the film, the grandson of the sheik pronounces the word sheik as "sheek". An Arab would almost certainly use the correct pronunciation of "shekh," as the correct spelling of the word is "Sheikh" due to the fact that "kh" is one letter in the Arabic alphabet and is pronounced as such.
Walter and his uncles are shown eating piles of sweetcorn harvested from their corn patch, but a later scene (Jasmine's burial) shows the corn still bearing tassels. Tassels emerge during pollination, and would have dried up long before the corn was ready to eat.
In the final scene before Walter hears the helicopter his hair is perfectly still and then begins blow as if the helicopter is right over him even though the helicopter has not yet appeared over the tree line.
