Revealing mistake: It was pouring when Adam, Hannah, and Megan got out of their SUV to talk to the Man and try to get help with the flat tire. As they stood there, no "rain" was hitting them and it became obvious that their partially wet-looking clothes were "pre-wet" - they returned to the SUV with the same amount of "wetness." Also, the rain was coming down in straight streams, all parallel. (The water flow appeared to be slightly angled to make the artificial "rain" look more natural).
Revealing mistake: Although the background scenery in the basement (behind the judge and Ron) changes with camera views, what is shown rarely (if ever) corresponds to the correct size and angle/location that would be expected. For example, the file cabinet in the corner behind Judge Straight shows up in different places, some very close to him and others at a distance; its size is not proportionate. Sometimes, the brick wall is directly behind the judge but to the right (of the screen) at other times. (00:03:28 - 00:11:29)
Revealing mistake: There is a large "Inglorious Basterds" poster on the wall of the building (to the left of the screen) when Roy and Betty stop at the bench along the sidewalk. The poster should still be visible when they resume walking, but there is a window in its place. (00:10:57)
Revealing mistake: When Anita goes to destroy their getaway car you see her pour gasoline all over the roof and hood. Then when she lights it on fire it's only burning inside the car. (01:06:40)
Revealing mistake: The five dollar bill that was tossed toward Todd's bucket but landed on the rim and hung over the side was obviously fake (not legal tender). (00:18:20)
Revealing mistake: The 3-light tree floor lamp in Soren's house (upstairs where Lucas and Thor encountered Hannah and Lily) has "fake" lights. Instead of seeing light from actual bulbs, each is simply a solid white circular shape. (01:16:30)
Revealing mistake: In Guatemala, when Arnie shoots John, in the shots from behind Arnie's body double is noticeable.
Revealing mistake: In the middle of the desert banquet scene, sand is lifted off the ground a second before the genie belches. (00:29:40)
Revealing mistake: The structure/set-up of Richard's house (front view) doesn't make sense and can't be real. The half of the house to the right of the screen is at an awkward angle and has no windows. What little of the roof that can be seen is flat - not conducive to snowy Massachusetts. The bottom of the door to the right of the garage door is inches above the driveway pavement (elevated with no step). The deck wall to the right of the yellow door is higher than the door but the front rails only reach halfway. (00:03:25)
Revealing mistake: The cement block section of the house by the front door that Greg was painting "changed" to a flat board for a short time and then went back to the blocks. (01:05:28)
Revealing mistake: When Shin begins chopping off Jay's head, in the close-up shot a line can be seen around the part of Jay's neck that hasn't been cut yet, revealing that it is a prop head. (01:35:05)
Revealing mistake: The way the outside steps were constructed - a series of perpendicular boards with no side support - would not be able to hold weight. They would easily collapse under pressure. (00:38:53)
Revealing mistake: When they're playing kickball the first time (when Phil sucks at it), the shots change from either the sun rising/setting to fog and cloud cover.
