6. Darth Vader's costume is related to the Holocaust

George Lucas created Darth Vader out of evil and darkness, and the costume had to reflect the evil essence of the dark lord. John Mollo was responsible to bring to life a costume that would represent this dark creature from head to toe.

Artist Ralph McQuarrie created a sketch of Darth Vader's costume – a bloated cloak and lugubrious breathing apparatus. Taking it from there, Mollo combined elements of various costumes with war and evil. The famous black helmet of Darth Vader is directly related with the headgear of the Nazis in WWII. And the breathing apparatus which resembles a gas mask is also suggestive in the context of a dark time in history ruled by Nazis.
