Another not-officially-announced-but-being-openly-discussed post-Endgame MCU film: Shang-Chi! This is another one that I don't really know anything about the property, but for the film itself:
- it is apparently filming in Australia sometime this year
- looks like it would be directed by Destin Daniel Cretton
- the script is being written by Dave Callaham
- will be the MCU's first film led by an Asian superhero
So, early days. Not a lot known yet, beyond that it appears to be happening.
