Just before Carla's litter is set down during the "White Virgin of the Nile" scene, the right rear servant's right hand is holding onto the littler pole over the top of the pole, with the pole clearly on his shoulder. Immediately, the shot goes to the servant lowering the pole, which is now off of his shoulder, with his right hand holding on underneath the litter.
While Clayton is playing the wacky characters inside the TV chassis in Sandra's bedroom. A frilly lace undergarment hanging from the window jamb next to the TV chassis changes position multiple times.
