When Dr. Bowen and Mr. Jones are traveling in the car down the highway after the hearing to the pier, they pass the same building and sign twice.
Mr. Jones's walk on the top of the roof at the beginning of the film has him walking South along the ridge. His 'reprise' of that same walk, at the end of the film has him walking East along a ridge. The whole roof line changed completely from earlier in the film. Construction on top of the gable is now not there.
