Since he's already Heimdall within this Marvel continuity, he will not be playing Black Panther. I agree, he would make an excellent choice but it won't happen. He's reprising his role for Thor 2 more than likely so it won't be him. I think Disney/Marvel might even have a stipulation in these actor's contracts that doesn't allow them to play more than one character within this continuity. Chris Evans can get away with it because he didn't play Johnny Storm within the universe that Marvel is creating on film right now. I have to go with many others and say Chiwetel Ejiofor. He was my second choice behind Djimon Hounsou, but he is in reality too old. Hounsou is 48, can't play it for too long. Ejiofor is 35, an excellent actor, has some moves as seen in Serenity, and has a regal sounding voice fit for a Prince of Wakanda.

I completely agree with D4Sale about Chiwetel Ejiofor who is actually the #1 actor on my list to portray Black Panther.

 Hey Tjanson, guess this Black Panther thing was news after all.

 I nominate Leo Dicaprio for Black Panther.

 now that Nolan's Batman is ending, I'd love to see Moon Knight and the Shroud appear in a film, as Marvel's answer...  maybe Night Hawk could appear as well...?   

Michael Fassbender is Black Panther.

Yeah actually my vote has been cast for Ejiofor. I wonder if they're shooting for a younger actor though.

Hounsou can play his father and Michael Clark Duncan is Man-Ape

Man I'd love a Moon Knight movie but the outward and superficial similarities to Batman may keep many away.

Totally different character than Bats. I'd pay to see it

 Michael Fassbender  has the penis to play Black Panther, I saw it in Shame.

My top picks would be Shaq, Chiwetel Ejiofor, Peter Mensah, or Anthony Mackie.  JK about Shaq.  I guess we will not be seeing Storm as BP's wife.  Bring on Terry Crews for Man Ape!

I still think Wesley Snipes could do it, at least be a father to the next one.
