Very sad on a personal level and profoundly sad on a cultural and professional level. A leading man actor dying at 43 means decades of lost work.
His performances included convincing portrayals of Jackie Robinson, James Brown, and Thurgood Marshall. He apparently did all of this and Black Panther while terminally ill. Remarkable.
I used to be a voracious watcher of film, not as much currently. But this is a true collective loss. Rest in power.
