Such a damned shame too. I was really looking for to the Black Panther sequel and more Avengers movies because when I was a kid, he rescued them in the Seventies from some gravity-based villain (I guess Magneto was busy). He was young, full of promise and I bet great roles were coming his way although James Brown and Jackie Robinson are tough acts to follow in American History, not just Black. The entertainer and baseball player pushed the envelopes on their prospective fields to make things better for everyone and Chadwick got to portray both!
I will close with this one thing he did for Alamo Drafthouse. Before Black Panther started, he was the special guest to remind everyone, “don’t talk during the movie!” Chadwick had this steely-eyed stare which let you know he meant it. So much that if you stayed through the ending credits, as per MCU tradition, you saw him one last time when the film “ran out” to give you a final “shush!”
Goodbye Chadwick! Thank you for everything and although your body of work isn’t as large as your contemporaries, you were a brave man. Fighting cancer while getting through the grueling MCU schedule! You will be missed enormously.
