Stan Lee was speaking at the Fan Expo Canada on Friday (via Comic Book Resources), and let it slip that the Black Panther movie indeed was happening (instead of being this juicy rumor that no one at Marvel will confirm just yet). When addressing the question of whether or not Scarlett Johansson’s Black Widow character soon will get her own solo movie, Lee explained:
The chances are she will have her own movie because eventually all the superheroes are going to have their own movies. They are already working on Ant-Man, Doctor Strange and the Black Panther, and there are others I am not allowed to talk about."

I know he also mentioned Doctor Strange but I think we all already knew that was coming.
