Star Wars Episode 5: The Empire Strikes Back - Luke's Head
While in the carbon freezing chamber, and Luke and Vader are fighting, Luke knocks Vader over the edge. Now watch carefully. Luke will jump down this apparent "long fall" but after you hear the "clink" from him hitting the ground, his head pops back up for a second before it cuts to the next scene. You'll see it in the bottom left corner.
