Plot hole: Spoiler: At the end of the film we learn that the girl is the wild animal, having been saved by the same doctor. Yet at the restaurant she is wearing a bare back dress and does not have the giant X-like scar on her back, like he has or the model has, who the doctor marries at the end.
Factual error: When Rob catches the Colombian guy with the drugs, the police officer tastes the drugs. In real life, a police officer would never taste drugs, because it could be something else, such as cyanide.
Visible crew/equipment: At the start of the film when Rob goes for his morning jog you can see a pad behind his left shoulder where he is supposed to get attacked by the dog.
