When Blair, Sackett and Frank are looking at the stepladder and see the dead cat, its body is shown next to the further foot of the ladder. In a later shot from a distance, the cat's body appears between the feet of the ladder.
When Frank and Cora first leave Nick, Cora falls in the dirt to avoid being hit by a car. All she lands on is her bottom. But the dirt keeps changing it's location in different shots, being sometimes on her shoulders, on the front of her skirt, completely gone when she sits on the suitcase, then obviously applied to her bottom as they are returning to the diner.
In the first scene in the new beer garden after the trial, Frank is shown holding a tray with 3 glasses on it, except he is holding the tray at such an angle that the glasses would obviously slide off if they weren't glued in place.
