The acting in this film was great as well.

This film was well done with just enough suspense to keep me interested. It had me guessing at times and there really weren't any dull moments. This film wasn't as bad as some people say it was. While the novel does have a scene showing Desi helping Amy to dispose of the car in a lake, such a scene is never shown in the film, so the car just disappears from the film without explanation. This would lead to the authorities checking out the surveillance footage of the casino where the car was left (which the casino would definitely have, so as to catch cheaters), and they'd see Amy being friendly, civil, and relaxed with her supposed 'kidnapper'. The car originally belonged to the Craigslist seller, and he'd definitely remember that he sold his car to Amy, as her disappearance became a nationwide media frenzy and he'd recognize her by memory. The car would eventually be towed by the tow truck company, and they'd naturally try to contact the original owner. She is found by Desi Collings at the casino and he takes her to his home, in his car, leaving her car behind at the casino.

She bought the car from a Craigslist seller, and picked it up in person, so the seller in question would definitely have seen her face. One piece of crucial evidence that could have implicated Amy, and be seen as highly suspicious, is the getaway car that she used.
