Directed by: Carter Smith
Starring: Jena Malone, Shawn Ashmore, Jonathan Tucker, Laura Ramsey
Factual error: When Mathias is getting his legs cut off, he's raising his head and shoulders off the ground, although his back is broken.
Suggested correction: Depending on where the break is, this is possible.
Revealing mistake: When Stacy exits the tent before cutting herself with the knife, the rock walls behind her "shake" like they are a set or projection. It's odd.
Trivia: Throughout the film, the five characters on the Mayan structure walk around in thin clothing day and night. In reality, it was quite chilly; the director and crew wore jackets to shield them from the cold.
