There are actually 2 inconsistencies that I found:

1. In the Paris hotel, after Corso exists the phone booth #2, :) "the girl" is wearing the green sweater underneath the black one, and in the next take, the green sweater is gone...

2. After Balkan kills Leanna, Corso runs out to the car, and "the girl" brings him his coat and bag. In one take, she is not wearing the scarf, but immediately after that, the brown scarf is around her neck...
