If fans have watched Iron Man 3 or looked up the spoilers on the internet, it's clear enough to understand that fans are very much not going to be happy with Shane Black for lying to everyone taking advantage of using the Mandarin just to hide the truth that the film's real main villain was an unpopular character known as Aldrich Killian.
The question is why?
Was it because Black and Drew Pearce were influenced from the scenes of Dark Knight Rises?
Because they didn't care about what fans want?
Or was it all because Guy Pearce is Shane's favorite actor?
One way or another fans going to want Marvel to produce a fourth film that will at least have what we want and just because Gwyneth Paltrow said that there is no Iron Man 4 doesn't mean she's telling the truth because she is not in charge of the films.
And sure enough if Ben Kingsley's character The Mandarin does survive in Iron Man 3, we hope that Marvel or whoever will be incharge of directing it will allow him to reprise his role so that The Mandarin in the Marvel Cinematic Universe will become the more powerful supervillain that we all know repectively in the comics by empowering his rings with the magic he dicovers from an alien ship and along with him should be the villain to make it happen, Fin Fang Foom.
Fin Fang Foom will appear in the film voiced by Clacy Brown from Jon Feavreau's Coyboys and Aliens.
The plot of the movie should be partially based on the Dragon Seed Saga of the Iron Man Comics
