Star Wars Episode 5: The Empire Strikes Back - Cauterizing the Wampa
In the scene where Luke is in the Wampa's cave, he slices off the Wampa's arm. He does this with his Lightsabre. Lightsabres are made of coherent energy and are so hot that they cauterize any wound they ,ake and so leave no blood. Both the Wampa's arm and his shoulder are bloody. There should not be no blood at all in this scene.
