Marvel One-Shot: First Look at Ben Kingsley's Mandarin encore (PHOTOS) | Inside Movies

Beware, Iron Man 3 spoilers lie ahead …

Trevor Slattery is ready for an encore. But it’s not always good to be the king.

Marvel’s latest One-Shot short film is aimed at a loose end: Ben Kingsley’s dim-witted Mandarin impersonator from Iron Man 3, who has been locked away in a maximum security prison and is reveling in his newfound infamy. (It’s as close to fame as he’s ever gotten.)

The 14-minute film All Hail the King was written and directed by Iron Man 3 scribe Drew Pearce, and will be included on the Thor: The Dark World Blu-ray, out Feb. 25. Entertainment Weekly has seen the movie and has the exclusive debut of four pictures from the short – plus details from Pearce about how it all came together.

The short is an epilogue to Iron Man 3 … but you could also see it as a possible prologue to Iron Man 4.

Each new film in the One-Shot series gets more elaborate than the last, and Marvel fans will be glad to know that All Hail the King ups the ante again. Most recently, we saw Hayley Atwell as Captain America’s leading lady Peggy Carter, battling bad guys and bullying bosses in the short Agent Carter, released on the Iron Man 3 Blu-ray in September.

Before that, Lizzy Caplan and Jesse Bradford were a down-on-their-luck couple using a salvaged alien gun from The Avengers to blast their way into bank vaults in Item 47. Both those previous films were directed by Marvel co-president Louis D’Esposito, and marked a step up from a smaller-scale pair of shorts on the original Captain American and Thor DVDs that focused on Clark Gregg as Agent Coulson.

All Hail the King features the biggest One-Shot star yet – Kingsley, whose character is one of the most controversial in the Marvel universe: a brokedown British actor who was only pretending to be The Mandarin, the murderous and ominous leader of The Ten Rings terrorist group.

The Mandarin is the classic Iron Man nemesis, and while some fans were amused by the curveball Iron Man 3 threw out there regarding his “true nature,” others were outraged and furious.

All Hail the King reveals — they are not alone.

“Imagine a real terrorist organization whose beliefs were long held and religious for thousands of years, and imagine a drunk, British actor coming along and essentially telling the world that he’s the face of your organization,” Pearce tells EW. “I think they would be right to be quite angry.”
