Alien - Chestbuster Classic

This is the special extended version of the scene, with extra never-before-seen cuts.

Probably one of the most recognizable movie deaths in film history. In the scene, known as the "chestbuster" sequence, John Hurt stuck his head, shoulders and arms through a hole in the mess table, linking up with a mechanical torso that was packed with compressed air (to create the forceful exit of the alien) and lots of animal guts. The rest of the cast were not told that real guts were being used so as to provoke genuine reactions of shock and disgust.
