Continuity mistake: When Sonny is giving Julian a bath, in the shots where Julian is closest to the camera, you can see a wide gap between the bath and the camera and even the side of the bath tub, as if it's in the middle of the room. In the shots behind Sonny, the bath is right next to a brick wall.
