Outside of Liu, no other cast members have yet been confirmed for Shang-Chi 2. It’s assumed that actors such as Awkwafina and Meng’er Zhang will be back for the sequel. Destin Daniel Cretton, who helmed the first installment, has been confirmed to direct Shang-Chi 2. The sequel is part of Cretton’s overall deal with Marvel Studios, as he is also developing a MCU show for Disney+
Shang-Chi 2 has been confirmed to happen, but Marvel Studios has yet to give it a release date.
Phase 5 is already packed as is with several upcoming films and shows. But there is the chance that Shang-Chi 2 may be one of the unannounced Phase 6 projects. If not in Phase 6, Shang-Chi 2 may not be happening until Phase 7 at the earliest. Cretton is also directing Avengers: The Kang Dynasty, hence the lack of progression on Shang-Chi 2. Even if Shang-Chi 2 is delayed till Phase 7, it feels safe to say the hero will be part of Phases 5-6 in some capacity. It’d be shocking if Shang-Chi doesn’t take part in the two upcoming Avengers films. Given Cretton’s Avengers: The Kang Dynasty involvement, it would make sense for Liu to be back for that film. Hopefully, Marvel Studios will provide updates about Shang-Chi 2 later this year.
