Go to the scene where Elle Driver is talking to Budd in his trailer. About halfway through Budd will start to make drinks for them in a blender. When he is done making the drinks he will pour them in jars and then set the blender on the counter. When that happens the camera will switch angles to show both him and Elle, but if you look back at the counter the blender has vanished.

Also for a more trivial slip-up look at the amount of drink he pours in the jars when in the first camera angle, the jars are half full at most. But when he hands one to Elle and starts drinking his own, the jars are almost full.
