Ryan Coogler garnered great acclaim for Fruitvale Station, and by all accounts his Rocky spin-off, Creed, is something special too - so it was probably only a matter of time before one of the big superhero studios came a-callin'. According to Heroic Hollywood, that studio was Marvel, who wants Coogler to direct Chadwick Boseman in his solo Black Panther movie.
There's no indication that Coogler is interested, however, and the site cautions that they're not sure if an offer has even been made yet, but we'll keep you updated. Marvel seems to have had some trouble locking a director down for this, so there could well be interest in other parties too.
The studio recently shifted the release date of Black Panther February 16th, 2018.
