Revealing mistake: When the elder Indian (Native American) with the black hat steps out of the yellow car at the beginning, and says hi to the shop owner, then Hi to the wooden Indian chief. You can see the Indian chief move slightly, indicating it is not a wooden statue, but a real person under the getup. (00:04:52)
Suggested correction: The scene where he moves is intentional. In fact, Old Chief Wood'nhead is played by Dan Kamin, and he moves a lot more later on.
Suggested correction: He does give a shocked look when he see's the statue move its head a bit.
