Upon first meeting Pursy, Bobby is lying in bed and Lawson is seated next to him preparing Bobby's drink. While Lawson prepares his own drink, Pursy and Bobby exchange dialog. During this dialog Lawson fills his glass twice without drinking from it.
Geraldine asks if Lorraine finally kicked them out. Through the smoke from Bobby's cigarette we see Lawson light his cigarette. After Bobby says God wouldn't let that happen Lawson lights the cigarette again.
Lee comes to visit Pursey, enters the house, sits down, props his feet on the coffee table and helps herself to a cigarette from the pack on the table. There is a very short break to a shot of Pursey and back again to Lee who now has a lit cigarette in his left hand. It was not possible for him to light the cigarette in the short time the camera was on Pursey.
The ship disappears out of the screen too quickly. While Bobby and Lawson are talking on the bank of the river, a barge goes across the screen. A close-up comes in for the men, but when it pulls back again, the barge is completely gone. It was a continual scene, with one conversation, but there was nowhere near enough time for the slow moving barge to get out of sight.
