Star Wars Episode 6: Return of the Jedi - Vader Is Supposed to Be More Machine Than Man
Forward to the battle between the emporer and vader. When Vader picks up the emporer, pause and slowly shuttle forward, watching the 'light' on vader's suit. When lightning hits, you see a clear outline of a full human skeleton. Not to bad for a cyborg whose mechanical parts refuse to show up on x-ray. :) Look at his hand when he gets it cut off. According to the cross section, the x-ray of the arm is totally incorrect.
