When Warren and Larry are standing on the street with their ferns talking it is initially a very overcast day with only a slight building shadow showing near the curb on the other side of the street. Toward the end of the scene it is suddenly a very bright day and a very visible shadow has moved 2/3 of the way across the street towards them.
When Warren and Larry are standing on the street with their ferns talking the woman in the blue dress with the brown purse passes in their background going from left to right and then passes them again going in the same left to right direction a short time later.
When Larry calls Carol at the bank during the robbery she is tied up and sitting toward the back of the bank between a man and another woman employee also both tied. In the next scene she is sitting 20 feet closer to the front door of the bank still tied up but behind a desk by herself.
