When you watch Marvel Studios' Black Panther and stay for the credits, you'll see that Donald and Stephen Glover were thanked for unspecified help with the movie. Donald, of course, appeared in Spider-Man: Homecoming, and the two are overseeing FX's Deadpool animated series - but it's not for that.
"Donald and Stephen actually gave me notes on a draft," Black Panther co-writer/director Ryan Coogler told Collider. "They came and took a day - they were really busy, they took a day and they read the draft and gave us notes. It wasn't that kind of a thing where it was 'change this, change that.' We were looking at ways to highlight a few more character things with specifically Shuri where she pokes fun at her brother. Donald's one of the funniest people that I know, so he had some interesting ideas. And Stephen's crazy talented as well."
Black Panther opens in North American theaters February 15.
