When Dr. Hogue is having his heart attack and Dr. Stone uses the defibrillator paddles on him, he tells Nurse Packard to set the machine to "400 Watts." Defibrillation magnitude is measured in joules and/or watt-seconds. While older defibrillators could deliver a maximum of 400 joules the model defibrillator shown in the film (a Physio-Control LifePak 5) could only deliver a maximum of 360 joules.
Ben hands Lou a small bouquet of pink flowers, which she informs him are protected because they are the state flower. South Carolina's state flower is actually Carolina jessamine, which is a flowering vine and it's yellow.
When Doc Stone realizes he needs to get the pig back he goes to Melvin's garage and then the butchers, both of these scenes are set in the dark, but when he picks Lou up its twilight. Yet all this happens in the same day.
(at around 10 mins) Doc Stone first walks into the hospital. There is no Time clock under Dr Hogue's Picture, but the next visit to the hospital about 21 Mins, we see the time Clock. It's not like the time clock was put there for Doc Stone because of his community service, there are several other time cards also.
In the restaurant, before and after the Mayor holds the town council meeting in order to increase Dr. Stone's pay, the catsup bottle moves closer to / further from the napkin dispenser between every shot. Also the orientation of the napkin dispenser changes from face on / side to Dr. Stone.
When Stone first enters the exam room while Dr. Hogue is having a heart attack, Hogue has his right arm (with the blood pressure cuff) down by his side. When the angle changes, the same arm is suddenly up across his chest.
The judge sentences Dr. Stone to community service as a doctor because he's "a licensed physician." However, since medical licensing is by state, it is highly unlikely Stone would just happen to be licensed in South Carolina.
When Dr. Stone is giving the injection to the guy fighting with the other one (during the house call montage), you can see water (or a liquid substance) splashing to the ground (on the right side, next to the guys head), therefore showing that it's not a real needle and not a real injection.
