Corrected entry: In the scene when Luke spends his first day on the road, at lunch, you see him laying down and there is a big tattoo of a mermaid on his chest. It is not there in the rest of the movie.
Corrected entry: At the beginning of the scene when Luke's mother comes to visit him, the position of her glass of water changes from one shot to the next. (00:39:26)
Corrected entry: In the scenes after Luke is returned to the road gang after his first escape, a large yellow van/truck is traveling on a road in the background. This type of vehicle and color were not available in the 1940s.
Correction: The film wasn't set in the 1940's; reference was made to fact that Luke was decorated for his service in the Korean War (1950-53), so the earliest setting would be mid-1950's.
Corrected entry: Luke uses an axe to chop the leg chain in half. He then uses the strips from his pants to tie the chains to his legs. He is shown only tying his left leg but when he gets up to spread the spices, both legs are tied. In the time elapsed he wouldn't have had time to tie the other leg.
Correction: They don't show him tying his other leg. But, that doesn't mean it wasn't done. Clearly, he had to have tied both legs since he is shown with both legs tied. It just wasn't shown, Time in film is neither linear nor realtime. Not a mistake.
Correction: That is not Luke, it's Warren Finnerty in his role as...Tattoo!
