Trivia: The film had been in some form of development since 2001. It was finally released in 2021 - twenty years after initial development began. (Although Stan Lee had campaigned for a movie starring the character as early as the 1980's, and he wanted Brandon Lee, son of Bruce Lee, to star in it).
Trivia: This film marks the debut appearance in the MCU of the classic Marvel villain The Mandarin. He was referenced all the way back in the first Iron Man film and was promoted as the main antagonist of Iron Man 3, with the iteration of the character ending up being a bait and switch. Part of the reason the character took so long to make it to the screen is because of the problematic stereotypes associated with him, combined with Disney's business partnership with China.
