A Fish Called Wanda (1988)

Plot hole: Shortly after the robbery, Kevin Kline and Jamie Lee Curtis get together in a little flat and Kline calls the police from a landline to tell them who committed the robbery. In England this would immediately lead the police to the flat from which the call was made, and the person reporting the robbery would be the first person the police would want to find and speak to. Otto has handed it to them on a plate. (00:12:29)

Plot hole: Archie goes from being waist-deep in a barrel of oil to walking onto the airplane and sitting next to Wanda. She greets him, etc. But there's no oil on his pants, no logical question by Wanda: What the heck happened?
