If it's successful material, then it has already validated itself. The burden then falls to the people changing the material in the adaptation to prove that the alteration is both necessary and better. Based on the outrage from Iron Man fans, both readers and movie franchise, Marvel Studios didn't do that with Mandarin.
Except Killian
IS Silver Age Mandarin, just painted white.
(1)The Mandarin the comics is a one-man version of the military industrial complex, a ruler who spends all his fiefdom's money turning himself into a person of mass destruction, a science and martial arts super-soldier. He basically spends the entire budget on the military, it's just he's the entire military. In the end his fiefdom is too broke to even pay taxes.
Is Kingsley's character, even if he had been a real, this? No, he's a terrorist, he's actually the opposite of the military industrial complex. In fact some of the things he says makes him out to be a victim of the military industrial complex, essentially their Magneto.
(2)The Mandarin is a mad scientist.
Is Kingsley's character, even if he had been real, a mad scientist? No, he's a terrorist.
(3)The Mandarin possesses superhuman martial arts abilities, the most common example of which is the ability to karate-chop chunks off of the Iron Man armor, and generally physically enhancing himself with chi. As corollary to this, he's extremely athletic.
Is Kingsley's character a superhuman martial artist? No, even if he were real, he's still a weak old man, entirely dependent on his organization to do anything physical of consequence.
(4)The Mandarin often schemes to cause world war III so he can benefit from everyone being at war with everyone else.
Is Kingsley's character, even if he were real, trying to get everyone to go to war with everyone else? No, he's at war with America himself. He seems to want some vague terrorist goal, it's never spelled out, but his bitter victim speeches imply he wants something comparable to America and Israel completely withdrawing from Palestine, something comparable to that if not literally that. Basically he wants peace to follow some anti-american political goal succeeding.
Kingsley's character fails The Mandarin test, and would have failed it even if he really was what he appeared to be early on.
Now let's try that again with Killian.
(1)The Mandarin the comics is a one-man version of the military industrial complex, a ruler who spends all his kingdom's money turning himself into a person of mass destruction, a science and martial arts super-soldier. He basically spends the entire budget on the military, it's just he's the entire military. In the end his fiefdom is too broke to even pay taxes.
Is Killian a one-man version of the military industrial complex? He's a member of the military industrial complex, he embodies the corruption of the military industrial complex to the point of caricature. He's using taxpayer money to turn himself into a super-soldier, and it's part of a scheme to get America spending even more money on his super-soldier program. While it may not literally make America flat broke by itself, his scheme is a massive example, a caricatured example, of the corrupt and bloated military spending that is causing America such budget problems.
(2)The Mandarin is a mad scientist.
Is Killian a Mad Scientist? Yup. It's right there from the moment he pops up.
(3)The Mandarin possesses superhuman martial arts abilities, the most common example of which is the ability to karate-chop chunks off of the Iron Man armor, and generally physically enhancing himself with chi. As corollary to this, he's extremely athletic.
Is Killian a superhuman martial artist? Welllll, yes and no. He's not literally superhumanly skilled, but he's superhuman and he uses karate-chops to chop the leg off one armor and chop another armor in half. He's not the Chi-channeling mystic monster comic Mandarin is, but for a simplified movie character he's fairly close. He's also played by a guy who is fairly tall and athletic, the star of several action-movies.
(4)The Mandarin often schemes to cause world war III so he can benefit from everyone being at war with everyone else.
Is Killian scheming to cause World War III so he can benefit from everyone being a war with everyone else? Yes and no, but mostly yes. He's scheming to control and render permanent the war on terror, which is to the modern world was World War III was to the 60's.
Killian passes The Mandarin test, or at the very least comes very close for simplified 2013 movie character. He certainly comes much closer than Kingsley's character, who would fail utterly even if he were not a fraud.
I post this because I keep hearing people claim that Kingsley's character, at least pre-reveal, was an authentic take on the Mandarin and I wonder what they mean.
