Trevor Slattery

Trevor Slattery is a character from the 2013 Marvel action film Iron Man 3. He is a drunken British actor who portrays the idealized image of "The Mandarin", under the control of Aldrich Killian, the real Mandarin. He was played by Ben Kingsley.

Early Life
According to his fictional past, the Mandarin's true name is unknown. He studied South American insurgency, Sun Tzu and other ancient warfare tactics. He later became an intelligence field officer, but due to witnessing the atrocities of the world, it drove him mad. He was also an expert in global intelligence and knew how to use the media to his benefit. He has a great hatred for America and used it to unify his group, the Ten Rings, who shared his hatred.

In actual fact, he is a British stage actor named Trevor Slattery. Trevor was forced to live on the streets after his drug habit bankrupted him, but Aldrich Killian came to him and offered him a new life in exchange for pretending to be "the Mandarin" for the cameras.

Iron Man 3
"The Mandarin" is the sinister head of the terrorist organization known as The Ten Rings, from which all the acts of extreme terrorism plaguing the world appear to emanate. Although he is reclusive, "The Mandarin" wields great power and makes his presence known by striking fear in the government and the populace through his brazen plans of attack. It is revealed, however, that the terrorist known as "The Mandarin" is nothing more than a front created by Aldrich Killian, as a means of covering the latter's illegal activities. In the final battle between Aldrich Killian and Tony Stark, Killian declares himself as the real "Mandarin" having masterminded the events that would lead to the attack on Tony's residence as well as Pepper's abduction. After the events in which Killian was killed, Trevor was apprehended by the authorities for assisting Killian's organization as well as his portrayal of the supposed terrorist leader.

Character Traits
The terrorist who was widely known as "The Mandarin" (as portrayed by Trevor Slattery) surrounded himself with Chinese iconography, dragons, and the symbols of warlords. He used many other warrior motifs and symbols and twisted them for his own use, such as Asian royal robes, a terrorist beard, samurai hair, a Captain America shield tattoo with the "A" for "anarchy" on the back of his neck. He also wanted to teach the world lessons, such as the fact that there was no such thing as heroes. Aldrich Killian described this idealized image of "The Mandarin" as being inspired by real life terrorists.

Behind the scenes
Kevin Feige quotes on the character adaptation of The Mandarin in Iron Man 3
 * This version of The Mandarin will not follow that same backstory, said Kevin Feige, the president of Marvel Studios. Don’t expect aliens, even though The Avengers and Thor opened up this unified cinematic world to the presence of extraterrestrials.
 * Iron Man 3 will be more about a clash of technology, Feige says and those who have been paying close attention to the previous two films know that The Ten Rings is a term for the terrorist group that kidnapped Tony Stark in the first movie, and gave the villain Whiplash some assistance in the sequel.
 * In that way, The Mandarin (who for a time was going to be the main villain in the first film) has been a part of the Iron Man series from the beginning, albeit as the off-screen manipulator.
 * "A lot of this movie is about characters going back into the shadows for various reasons and characters who have been in the shadows coming out and into the light for the first time," Feige says. "It is Tony who, for various reasons, finds himself receding into the darkness. I don’t mean emotional darkness, I mean literally ducking out of the spotlight. And we’ll see other characters stepping up who have pulled strings from the background, starting to show their hand."
 * Kingsley is not, of course, Chinese, but Feige says they wanted to blur the background of this version of The Mandarin. "It’s less about his specific ethnicity than the symbolism of various cultures and iconography that he perverts for his own end," Feige says. From his samurai hair, to his royal robe, to his bin Laden-esque beard, and the AK-47 he keeps at his side, Kingsley’s interpretation is a hodgepodge of various warrior motifs.
 * In his attempt to rid the world of its oppressors by replacing them, The Mandarin considers himself a twisted version of absolute good. "Don’t all good villains?" says Feige.
