When the train scene comes up, Dickie comes into Charlie's and Irene's cabin, Charlie was in the toilet and Dickie comes in, Charlie is now Hank and pushes Dickie and he drops his gun out the window and Dickie turns around and hits Charlie, when he falls on the bed, Irene hits Dickie over the head with a dildo, he falls on top of Hank and you can clearly see Hanks' shoulders. When they zoom in, Dickie is completely over Hank and you can not see his shoulders, coincidence, I think not.
