Crew or equipment visible: When Samantha flips the jeep, and the camera is on Amanda,you can see a crew member walking in the shot through the back window.
Miscellaneous: During the scene where they are searching for the snake in the abandoned warehouse, there is electricity still on.
Continuity: When one of the 2 jeeps explodes, the front side of the jeep is on fire. When they hunt for the snake and Pinkus stays behind them, only the rear side of the jeep is on fire - the front side is shiny white and clean again.
Revealing mistakes: It is stated that the enclosure housing the snakes contains 3 inch thick glass. However, after the glass is broken, there is a shot where you can clearly see the width of the glass is not even an inch thick.
Revealing mistakes: The "SAT phone" is actually a Nokia 92xx Communicator. The earpiece is just above his forefinger.
Revealing mistakes: When Amanda is burning her files at the end, a clear shot of one page is seen. Not actually secret snake formulas, it is in fact a collection of chemical reactions one might see on an exam for first semester organic chemistry (elimination, bromination, ozonolysis, hydroboration, etc.).
Continuity: After Amanda falls in a mud puddle, in the next scene she is seen washing her face in the sink of the farm house. Her hair and clothing are both clean and not out of place or stained at all.
Continuity: When they arrive at the farmers place, the house front door is open. When they walk up to examine it, the door (as well as the thin mosquito door) is now closed.
