A still from The Thing, just when they discover some thing under the ice. "It's round. It's perfectly round."
Alphaville (1965), directed by Jean Luc Godard
Baby from "Alien" Stomach , I remember the scene well. Best in movie. He seems to have no bad effects after the pod animal is removed from his face. He even enjoys a meal, then pop goes the baby from his gut.
