Near the beginning of the film, you see Sophie touching up the painting inside the owl's eye. The next shot clearly shows her over-blacken part of the white in its eye. In the next scene, it is untouched.
The camera follows the car into the tunnel heading east, and when the car exits the tunnel it is heading west. Furthermore, the car wouldn't even enter the tunnel for the trip being made.
When Mara is seducing Sophie's husband, after Mara is being undressed you then see that Mara is still dressed when they continue to kiss as the phone rings.
At the beginning of the film where Sophie is in the Kitchen cooking, she picks up a pepper grinder and shakes it into the pot from the wrong end.
When Sophie is reading the letter addressed to Mara, the address given is Middle Park, 3185, Victoria. The post code for Middle Park is 3206, not 3185. 3185 is the post code for Ripponlea.
