Twist looking out the window toward the drug store
While Hooker is waiting for Lonnegan in the drug store there is a straight on shot of Twist looking out the window toward the drug store. Twist is using his left hand to move the drapes aside, but when the camera angle changes to an over the shoulder view he is now using his right hand. Same thing happens when Hooker leaves the drug store after his meeting with Lonnegan.
"Gubmint do take a bite, don't she?"
