If you didn't already know this, Donald Glover got his Childish Gambino rap name
from an online Wu-Tang Clan rap name generator.
Also Ghostface Killah, AKA Tony Stark,
almost got a cameo in Iron Man, (the scene was cut) partly because back then when he took the Tony Stark name, Iron Man was still a second-tier Marvel property.
Also if you haven't heard the album
Liquid Swords by RZA and GZA, it is really good.
Thanks for the heads up about the series!
