This Isaiah Mustafa Old Spice guy was born to play Luke Cage. Actually, Mustafar Spice there is probably a better fit than the character deserves.
Not super familiar with Luke Cage, though he does have a small role in the recent Fraction/Brubaker series The Immortal Iron Fist, which was spectacular (the series that is - the cameo was just ok).
Get hip to the Iron Fist scene with the hefty 560 page Omnibus edition.
