If you guys agree with this suggestion please contact Kevin Feige to have the Russos bring Downey back for Avengers 4 and make sure they do NOT kill off Iron Man because they still promised us the real Mandarin in the future of the MCU and it's better to have the redundancy done instead of keeping us waiting for an unbearable amount of decades for the people to reboot the films. Plus Iron Man 4 should be Downey's last Marvel film and by having Byung Hun Lee cast as the real Mandarin of the Ten Rings and done right exactly as shown from the pictire in this article above. This time, they are to do the power rings and not screw around with the character in any severe way like they did in Iron Man 3 or worse. After all with all the magic of such special effects being done in the Marvel Cinematic Universe and everything being done far beyond reality with anything possible, Kevin Feige and his staff have no reason to back out from doing the power rings over any nonsense of such disbeliefs and they don't need the Mandarin being a chinese dictator. They just need him to blend in with the more civilized world of the MCU and make him a korean or an asgardian from Vanaheim wearing the magic black armor and the power rings in hand.
Now here are the cast you see in the picture:
Robert Downey Jr as Iron Man
Byung Hun Lee as Mandarin
Italia Ricci as Bethany Cabe
Don Cheadle as War Machine
Oscar Issac as the second Ghost
Mark Wahlberg as Arno Stark
Sebastian Stan as Winter Soldier
David Thewlis as Kearson Dewitt
and Roman Varshavsky as the Mandarin's 3rd in command Lieutenant
There, now please let's make sure this 4th installment happens!
