In the conversation with Maydig down by the river, Fotheringay places his cane on the log and rests his hands on it and also takes his cane off the log. There are several discrepancies in the relative positions of Fotheringay, Maydig and the cane in the cuts between these shots. There are also shots of each character by himself which it would be impossible to take if they were actually in the positions shown in the wider shots.
In the final scene in the pub, Fotheringay is shown with his hands on the bar as another patron addresses him, but in the next immediate shot, his right hand is up to his cheek.
The sequence in which the constable is transported to San Francisco was obviously filmed in Los Angeles.
