I am amused by the character Carl's hair dye. In the house he has the notorious "blue" hair. Back in the 70s, 80s the gray haired elderly, most commonly ladies, would dye their gray hair and intentional or not, their hair would have a blue hue. Ergo the saying "blue haired ladies clutching their pearls". Carl's hair is most definitely blue hued. Now turn to the scene where he's hanging in the barn and his hair is suddenly transformed to brown. I would've never noticed the change until I started reminiscing about my grandmother's gray hair back then which did not have the blue hue. And then there was Carl all of a sudden with brown hair, not a lick of gray or blue.
