Other mistake: When Lorne Malvo shoots out of the window the only thing sticking through the newspaper is the gun's barrel. When the shot changes to the scope view, you can see the outside. But you shouldn't be able to look outside.
Other mistake: In the scene in 1987 which takes place where the movie did, the location of the case of money is different than it was in the film. In the film there were no power lines and it was on the opposite side of the road. The sun angle can be used as a reference. The film and this part of the episode were supposed to take place in the same spot.
