Advertised and disguised as the Mandarin, Kingsley’s character is revealed in Iron Man 3 to be no more than a drug-addicted actor named Trevor Slattery who is used in as a decoy in Iron Man 3 - a fictional terrorist of sorts to take the blame (and news headlines) for a series of attacks and events orchestrated by the true antagonist of Iron Man 3 - Guy Pearce’s Aldrich Killian. By the end if the film, Killian is seemingly killed, while Slattery lives on, seemingly in custody.
Speaking with the Belfast Telegraph, Kingsley confirmed that he’s returning to Marvel for an undisclosed project, one where he gets to work again with the Iron Man 3 crew.
“It’s a secret Marvel project. I’m not allowed to say any more, you’re going to have to wait and see… I was with many members of the crew that were involved in Iron Man 3. It was lovely to see them again. It was great to be with this wonderful family.”
“I think they have enormous taste as creative artists. There’s nothing lazy or gratuitous about their work. They are at the top of their game, and they’re great company to keep.”
Here’s a thought. What if somehow he appeared in Agents of SHIELD. They could play up something for laughs.
