This slip-up is when Max first meets up with the kids. As they just leave the mom to go up the mountain, one of the kids says Why didnt you bring a pack. Max says what do you mean i did bring a pack. And reaches for a pack of cigs. As he puts the last cig in his mouth he crushs the pack and tosses it behind him. The girl scout says your not gonna leave that here are ya talking about the cig pack. As the camara takes a shot of what she is talking about they show the cig pack. But some how it's not crushed its as if someone placed it there.. it's pretty easy to see.
