3. Will Smith

What else has he been in?Hancock, Ali, I Am Legend, In Pursuit of Happyness, Independence Day, Bad Boys I & II, Men in Black I, II & III. Fresh Prince to Wakandan Prince? A lot of people would laugh off this idea, but I happen to think Will Smith is actually a very good actor and could pull this off. Smith has unrivalled charisma, good looks, is naturally fit and proved in his Oscar nominated performance as Muhammad Ali that he can perform character acting to a a very high standard. And his portrayal of Hancock shows he can do the superhero thing - although Hancock is admittedly a
very different kind of hero to Black Panther. He is 44 years old, but still at the peak of his career and undoubtedly the kind of star name that would bring in the viewers, but whether or not he's actually on the list of potential candidates drawn up by Marvel is highly questionable.
