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.
Continuity mistake: When Marvin walks Rianna home after dinner, she stands in front of her door and crosses her arms asking him if he wants to come in. The camera angles from the front show her arms crossed, the ones from the back show her arms at her side. Happens throughout the scene.
