Factual error: At the end when Ben Willis and his son have Julie at the graves, Ray shows up with a gun. He fires at Ben but there is no bullet in the chamber. Later after the fight between Ray and Ben's son Julie picks up the six-shot gun and fires 8 shots at Ben.
Factual error: Ray escapes from the hospital. The machine he was hooked to wouldn't go off like that causing panic. It would simply show "leads off".
