A little explanation is due. "Don't jump as you screw!" was delivered to the Clown in a scene where, trying to hide a bundle from Autolycus, keeps shrinking and "screwing" himself into the floor as Autolycus circles quasi-menacingly about him. On the inital run of the scene, the Clown was turning in jumpy, jerky circles rather than the smoother, gradual twisting-down that we wanted. Hence the reprimand.
See, it's not so bad. Actors really aren't thatimmoral.
