Director: David Twohy. Cast: Steve Zahn, Milla Jovovich, Timothy Olyphant, Kiele Sanchez, Marley Shelton, Chris Hemsworth.
This is a very dishonest film, and I despise dishonest films. It is focused around a mid-movie story twist, which could have been a very interesting plot device in the hands of another screenwriter/director. But the filmmakers shamefully use extra misleading scenes and dialogue to make the story twist believable at any cost (e.g., if that couple were really who they turned out to be, why were they saying such and such in private?). In other words, the movie is cheating. Stay away to protect your intelligence from being insulted.
Warning: David Twohy is also the director of the two Pitch Black movies. The moral of the story is, avoid all David Twohy movies. Something similar to Uwe Boll.
