When the whole family is having dinner, Augusto is seated at one corner of the table and the mother is sitting on a side at the other corner. The cat is shown to be eating meat off the mother's plate in one scene, but in the next scene Augusto is shown picking up the cat as if was right next to him on the table. Once he removes the cat, the next camera angle again shows Augusto and the mother at opposite ends.
During the final scene when Alesandro is having an attack, you can see the camera shadow several times; for instance on the bed.
