Factual error: This movie is set in 1935. Back then, executions were done by hanging. The Louisiana Legislature changed the method from hanging to electrocution in 1940.
Factual error: The cell keys carried by the guards do not date to 1935.
Factual error: When Paul returns home, his wife asks him what the doctor said. He replies "...gobbledygook mostly." The trouble is, the word "gobbledygook" wasn't coined until 1944. This scene takes place in 1935.
Chosen answer: Percy's aunt is married to the state Governor, giving Percy powerful connections. All it would take is one phone call from Percy and Paul and the other guards could lose their jobs and if Percy wanted to, never find jobs again. Something Paul or his friends didn't want to happen.
The characters talk about this several different times in the movies, how political connections can ruin careers.
