Lol... there should be a one-hitter-quitter moment against a perceived-to-be-an-even-match opponent just for laughs and uberness.
Also, speaking of physical performers, I also think they should get Sebastian Foucan in on the stunt work, he's a father of Parkour, and was featured in the opening scenes of Casino Royale.
And though he'd love to be the actual BP, I think I'd want to see Michael Jai White as a fight coordinator, assuming he could work well with the parkour guys, which I don't really doubt:
Other off camera roles running through my head:
Producers: Feige, Stan Lee (of course), Reginald Hudlin, maybe Deznel or Forrest in order to get them involved as T'Chaka.
Writers: me and roach, or similar
Cinematographer: Ernest Dickerson... he's been in the director's chair for a few years on TV shows like walking dead, but it might be interesting to have him in this role on a film...
Antoine Fuqua is still rising with his Olympus Has Fallen... he's more and more my favorite director for this project. If he did something with any kind of serious melee combat or superhuman/superhero aspect, he'd be nearly ideal, imho. He's got Africa down (Tears in the Sun), he's got the royal rising stuff down (King Arthur), He's got political action down (Olympus has Fallen), he's just generally well positioned, and relatively consistent and improving (with the possible exception of Brooklyn's Finest).
