They have a black Superman movie from 1997, it's called Steel and starred Shaquille O'Neal.

Seriously, there's nothing wrong with that character, and if Warner Brothers had developed a long-term plan instead of just throwing out the Synderverse movies as fast as possible, they could have actually made another Steel movie riffing off the Reign of the Supermen storyline.

Now, it's probably too late. The MCU is collapsing under its own weight as audiences prove that giving C-Tier characters their own movies doesn't pay off, and superhero movie fatigue is setting in across the board.
