So regarding black panther

So regarding Aliens. Not a single frame was shot on Acheron.

So regarding Lord of the Rings. Not a single frame was shot in Middle Earth.

It takes place on a fictional continent, do you want them to just raise land out of nowhere?

So regarding "big sausage pizza 24" no one really ordered a pizza with a wang stuck through it.

They probably didn't want to film in a shithole country.
^(this is a joke by the way)

African pride is an oxymoron

Grimsby was filmed in Essex.

So, regarding D. Gray-man. Not a single frame was drawn in the 19th century.

This is not nearly the same thing. Filming in Africa would have been feasible.
