I instantly thought of Sacha Baron Cohen as The Dictator when I first saw this poster of Ben Kingsley as the Mandarin in Iron Man 3. Either that or as a rapper in Master P's No Limit army. Either way, man he is looking gangster.
According to the Marvel Wikia, here's a little background on this guy:
The Mandarin's parents died shortly after he was born. The Mandarin spent all of his vast inheritance training at science and martial arts. Doing so caused him to go broke at roughly the same time he reached adulthood. The Chinese government evicted him because he was too broke to pay his taxes. The bitter, broke, homeless, but extremely well trained Mandarin began to wander the earth. He found an alien space-ship during his wandering. He studied the ship to gain knowledge of advanced science, and stole rings he found within it. The Mandarin uses a combination of superhuman martial arts abilities, alien science, and the ten energy-blasting rings he found to wage a never-ending war on civilization.
So this is the guy that will be all up in Tony Stark/Iron Man's business in the new film, come May 3. Check out the full poster below.
Marvel Studios' Iron Man 3 pits brash-but-brilliant industrialist Tony Stark/Iron Man against an enemy whose reach knows no bounds. When Stark finds his personal world destroyed at his enemy's hands, he embarks on a harrowing quest to find those responsible. This journey, at every turn, will test his mettle. With his back against the wall, Stark is left to survive by his own devices, relying on his ingenuity and instincts to protect those closest to him. As he fights his way back, Stark discovers the answer to the question that has secretly haunted him: does the man make the suit or does the suit make the man?
