Continuity mistake: When the kids are looking at the Stonehenge-type structures, the younger boy calls for everybody to come and see the hidden message. From the shot in front of the boy you can tell from his body position he's sitting up, however in the next shot from overhead, the boy is now lying down on the rock.
Factual error: Narration refers to Hitler's Germany research into nuclear fusion - it was nuclear fission they were looking into, the same as what fueled the WWII-ending bombs in Japan, and every nuclear bomb and missile since. No nation has been able to generate nuclear fusion until very recently, and it doesn't produce an explosion - which is what Hitler wanted. (00:08:35)

Continuity mistake: During the scene of the first meeting between Gus and Ruby, Krysten Ritter's hair moves back and forth (behind or in front of her left shoulder) between shots multiple times (most obvious example: when he offers her a drink). (00:12:45 - 00:14:35)
Revealing mistake: About seven minutes in, during the scene where we see Cooper helping the Nerd as a cameraman, you can tell that Cooper has been added to the scene using green-screen effects, as the actor was unavailable to shoot at the location.

The guy is named "Grigori Babishkova", which is laughable since "-ova" is the female suffix for Slavic last names, he should be "Babishkov." The Nationality field lists him as being "Russian/Caucasian." Caucasian is not a 'nationality'. (00:05:05)
Plot hole: When Mr. Shepherd arrives at the school he learn Joseph's (the student's) name but loses his memory. When they are telling him the nativity story Shepherd says "this Joseph" when referring to the student, but he shouldn't remember it.
Continuity mistake: The students' 3rd game is Kagome with 4 Kokeshi dolls. The pink doll starts to the right of the first student to play, the dolls move in a circle around him, she passes in front of him and by the end of the shot she is near his left. The Kokeshi dolls all move backwards between shots and the pink doll passes in front of the student again. After this, she takes 7 seconds to move about 100° despite nobody slowing down and she took that amount of time to move about 170°.
