Continuity mistake: Walter tore out the newspaper article ("Body of Woman Found at Greenland Rest Stop") fairly neatly/evenly; it was relatively straight across the top, though a little jagged as could be expected. When Walter looked at the article some time later, the jagged top was worse and there was MORE space between it and the title. The right side also appeared to be more jagged than it was and include a little more of the article that was to its right before being torn off. (00:07:03 - 00:13:37)
Revealing mistake: The "snow" is obviously fake and it is largely absent on the left third of the screen and, to a lesser extent, the right side. Although it apparently recently started snowing, the snow was not melting when it hit the pavement, which would mean it was cold enough for snow to also "stick" onto metal vehicles (but did not) and the car pulling into the alley should have left tire tracks. At various spots throughout the movie, "snowfall" is spotty and irregular. (00:26:48)
Continuity mistake: When Kimmel was eating his steak, the position of the three beer bottles near the upper-left hand corner of the table changed. At first, they were close to his plate (two almost touching) and arranged like the first three bowling pins would be. A front view shows the three beer bottles further away from Kimmel's plate and at a different angle. (00:36:43)
Deliberate mistake: It is unlikely that Kimmel shoving/ramming the beer bottles on the table using his dish and piece of steak in his right hand would shatter the beer bottles into such small pieces (or at all) like he did. (00:36:55)
