Black Panther is still a popular Marvel film months and months after its release last February and there is already some talk that it may become a major awards contender.
The popular Wakanda characters made a return to the big screen soon after in Avengers: Infinity War and will be returning for a sequel at some point in the future (not to mention making another appearance in Avengers 4).
Doubtless merchandise for the movie is popular given the right contest.
