At some points, certain directors can find a way to make a particular actor shine. Think Scorsese and DiCaprio (or Scorsese and De Niro, for that matter), or Spike Lee's work with Denzel Washington. Ryan Coogler and Michael B. Jordan are embarking on a similar working relationship, to the point where Coogler's three feature films (Fruitvale Station, Creed, and Black Panther) all feature Michael B. Jordan in a starring role.
At ComplexCon 2017, Jordan spoke about trusting Coogler with his well-being during their projects and credits Coogler with giving him the "self-confidence" to take up the mantle of directing himself. That doesn't mean the pair are done working together; Coogler's upcoming fourth film, Wrong Answer (about a 2013 standardized-test cheating scandal in Atlanta), is set to star Michael B. Jordan and is being authored by Black Panther comic book writer Ta-Nehisi Coates.
