The real Mandarin is going to be in Shang-Chi: Legend of The Ten Rings and will be played by Tony Leung. One of Marvel Studios' most controversial decisions came in Iron Man 3 as it was believed that the legendary Iron Man villain Mandarin would be involved. Ben Kingsley was set to play him, but it was all a ruse, as he was instead a washed up actor playing the part for Aldrich Killian's (Guy Pearce) schemes.

However, the All Hail the King Marvel One-Shot confirmed that the real Mandarin does exist in the Marvel Cinematic Universe. Fans have been left waiting and wondering if that tease would ever be paid off ever since. When it was revealed that a Shang-Chi movie was in the works, many theorized that this could be Marvel's opportunity to actually use the Mandarin - and now they've confirmed that's the plan.

During Marvel Studios' Hall H presentation at San Diego Comic-Con, they confirmed that Tony Leung will play the real Mandarin in Shang-Chi. Leung is an incredibly famous actor who is best known for his work overseas in films like In The Mood for Love and Infernal Affairs.

Confirmation that Mandarin is going to be part of Shang-Chi: Legend of The Ten Rings will finally bring closure to one of the MCU's biggest mysteries. It also means that the popular theory that the MCU will make Shang-Chi's father the Mandarin a real possibility, even though that was not confirmed during the presentation. Even if that doesn't happen, the Mandarin will clearly have a big role to play in the movie based on the subtitle. The Ten Rings could refer to the organization the Mandarin leads and/or the incredibly powerful, magical artifacts he wears. Either will make Mandarin central to the story that Shang-Chi will tell.

This is, however, just one of many pieces of Shang-Chi related news to come from Marvel's presentation. They confirmed that the movie will be their first to hit theaters in 2021 and added more cast members to the Destin Daniel Cretton-helmed movie. Simu Liu landed the leading role of Shang-Chi after only just recently screen testing for the part, and they also confirmed that Awkwafina will have a role in the movie, too. The excitement may have ended there as far as Shang-Chi: Legend of The Ten Rings is concerned, but Marvel Studios revealed an abundance of news about their plans for all of Phase 4. Check out the rest of Screen Rant's coverage of their panel to catch up on all the exciting revelations.
