When Snake Eyes drops the dice on the coffee table the first time a "6" is visible on the side of one die. When the camera shifts to overhead both dice show a "1". This is not how dice are made. Each opposite side adds up to 7, thus one of the dice would not have a 1 on top.
UPDATE - Not all dice are set up this way. Another common layout is referred to as Spin-down, where sequential numbers are on adjacent faces. In that layout the 6 is adjacent to the 1 and opposite the 3.
The easy way to tell spin down dice from regular - spin down dice have 20 sides.
