Corrected entry: As Marianne and the Reverend drive past the large accident scene, shots on Marianne's face show her emoting and acting, but shots on the Reverend show that she is rather passive and calmly looking forward. (00:26:25)

Continuity mistake: When Paul is introduced at the hospital, in one shot he thinks, "What am I doing in this precorpse club?" and turns his head to his left. In the next shot, he is turned to the right, and the shot after shows him turning from his left to his right. (00:04:45)
Paul Rivers: They say we all lose 21 grams... who will be next?
Trivia: The experiment that showed that humans lose 21 grams at the moment of death were later shown to be highly flawed. The entire experiment was based on only four people. Only the first subject actually lost 21 grams. Another person lost a different weight, and the other two died before they could be properly weighed.
Answer: The title refers to an experiment in 1907 which attempted to show scientific proof of the existence of the soul by recording a loss of body weight (said to represent the departure of the soul) immediately following death. Referred to as the 21 grams experiment as one subject lost "three-fourths of an ounce" (21.3 grams), the experiment is regarded by the scientific community as flawed and unreliable, though it has been credited with popularizing the concept that the soul weighs 21 grams.

Correction: He probably wasn't watching the scene, because he was driving the car, so, at least in my personal experience, not all drivers like to be looking at any other thing than the street ahead of them as driving (except for the mirrors), and taking your sight to something as an accident usually isn't such a good idea. He might also not see it, because he might not want to see it, he probably just made Marianne the favor, and he might be disgusted or perturbed by the scene, preferring not to watch it.
