Marvel meeting a hypothetical diversity quota does not hinge on the existence of a black widow movie (or a black spider-man for that matter)
We have black panther and captain marvel movies in the making.
We have a Jessica Jones show filming right now
Falcon and War Machine in the MCU
An Asian Hogun the Grim
A black Heimdal
Another tv show with two female leads of Asian descent
Could we please stop talking about Marvel and their supposed lack of diversity?
Plus a Luke Cage show next year. Marvel has really done a solid job of shoring up a great new cast of characters to keep the MCU going.
