the director and others get tested for COVID-19.
The character of Shang-Chi was first introduced to Marvel Comics in 1973, as a master of martial arts. He was raised by his father, Fu Manchu, an immortal sorcerer and crime lord, to be a deadly assassin, but instead, Shang-Chi chooses to fight for good. After his initial run, he has appeared as a ing or guest character in other series and has fought alongside the Avengers multiple times. The film will most likely be an origin story for the character.
According to The CW have done the same.
Shang-Chi and the Legend of the Ten Rings is Marvel's first film with an Asian lead. The movie has an Tony Leung (In the Mood for Love) as the real Mandarin, the leader of the Ten Rings terrorist organization.
This halt of production is a significant loss for Marvel, but it will most likely be worth it, given what they will make when Shang-Chi finally releases. The film currently has a release date of February 12, 2021, though that is likely to change if this hiatus continues. The Falcon and the Winter Soldier's production has also been halted, and the Loki series is expected to do the same soon. Although this will possibly push the release of the film back, Shang-Chi has a talented and capable cast and creative team bringing this story to life, and it's sure to be worth the wait.
