Continuity mistake: In the scene towards the beginning where pair- chained interracial prison escapees Noah Cullen and Joe Jackson (Sidney Poitier and Tony Curtis) are trying to cross a river together without killing each other, they get carried away downstream and are stopped by a tree. The mistake is, Sidney Poitier's bald headed stunt double is noticeable losing control while floating downstream, visibly and audibly crashing head first into the tree. He is briefly flailing and struggling from the unexpected impact until Sidney Poitier reappears properly floating towards the tree without struggle. This mistake is less than 30 seconds and is awesomely noticeable best on Blu-Ray disc. The shot of Tony pulling Sidney out of the river concludes the scene.
