Other mistake: Abraham's wife appeared to hit him with the vase on his right shoulder, but Abraham put his hand on the side of his head. (00:58:35)
Continuity mistake: Before Abraham stands near the wooden cross, there are piles of wood and a blue/white water hydrant (?) behind him. When he stands and takes a step, only one pile of wood is visible. After he takes a few diagonal steps behind the cross and turns around, he is standing in front of his house that was not there. (The house should have been visible when he was sitting near the cross). (00:45:51 - 00:46:12)
Deliberate mistake: Abraham is sitting to the right of and slightly behind the cross he hammered into the ground, but is about 3' away. When there is a close-up, Abraham is much closer to the cross - the end of the crossbar to the right is directly above his shoulder and his knees appear to be close to the vertical bar. (00:45:15)
