When the first trailer of Iron Man 3 hit the web, everyone was excited to see Ben Kingsley portraying Iron Man's arch enemy, the Mandarin. But when the twist over the character's appearance started to happen, lots of fans were upset that the Mandarin was not who he really was suppose to be that other than making Kingsley's Mandarin a decoy they unthinksbly made the real Mandarin some lousy ripoff that does not use rings at all and that is what really makes the twist a complete error in the Marvel Cinematic Universe. The reason why Kevin Feige and Shane Black purposly made this irratatingly unacceptable twist happened was all because of the character looking like Darth Sidious with the hood, being considered a racist, and worst of all they took away the power rings over their selfish opinion about the character that they felt like using the idea people using people as mask theory instead but it was bad idea. Nothing good about it at all when doing it on one of the best villains.
Forturnately with Kingsley's character still alive there is a chance that Marvel will have him reprise his role so that his character becomes the proper 10 power ring Mandarin for real this time by having him return as the leader of the Masters of Evil with Crossbones, Abomination and an unconfirmed villain from Thor the Dark World at his side against the Avengers and that the 10 power rings are given to him by Thanos and will be sure to return in Iron Man 4 with the debut of Fin Fang Foom and I'm sure that with those two characters in that movie and if all of you read the popular Iron Man comics of 1991, you should all know what to expect.
But if Kingsley is not summoned back to reprise his role, then Marvel film executives need to cast a new actor to play a newly reintroduced Mandarin that does wear 10 power rings and is the true Afghanistinian leader of the Ten Rings terrorist organisation in Iron Man 4. That way Aldrich Killian will be considered another actual decoy and that the real Mandarin had him cover for him since Tony escaped Raza in the first film, and the best known actor to play the new and more proper Mandarin it is Oded Fehr
Oded Fehr is known for his film appearances in films like The Mummy and Resident Evil and is also known by fans for occasional voice acting in shows like Justice League, and Duel Monsters. So if Oded does get casted as the new and more actual Mandarin in Iron Man 4, he would definately do a much better job than Kingsley and Pearce.
