"Black Panther". Of course it's way too early to say who would play the part but it's been speculated that Adewale Akinnuoye-Agbaje (GI Joe) and Djimon Hounsou would be likely choices. I would love to see Marvel make this movie before the wave (or fad depending on how you see it) of making superhero movies comes to a close. If you saw Iron Man 2 you might have noticed a few easter eggs that could speak to future plans for the Black Panther movie or at least an Avengers film. Let's hope this project gets off the ground sooner than later.
