Near the end of the film cars can be seen driving past on a road less than 50 meters from the cannibals' supposedly remote village.
Due to the very limited budget, the extras hired as cannibals don't look like jungle people at all. Their skin colors vary wildly, some are extremely pale, like they haven't seen sunlight in years. Their hairstyles are also 70's city men hairstyles, one of them even has sideburns.
During the end scene, one of the natives is on his knees being kicked and berated by the chief. As he crawls, blue cotton underpants can be seen poking out from his loincloth.
When Mickey takes the Jerry Can from the car its green with yellow lid, when she is running through the grass, its green first time, then it's an white/transparent.
The guy playing the part of the little girls father is old enough to be her great great great grandfather and is too old to be having children that young.
