Go to the part where roy is hustling (when he's younger) with big ernie, and carefully look at the seat ernie's in. Earlier, he was in the left seat, but then he's in the right one from the back view.
LOL. Ok, someone can't tell left from right. Yes, when you look at him, that's your left; but, when your BEHIND him, he is on the right. If you are looking at someone's face, your left is actually his right.
