When he passed I said dont recast him because it was too soon and now I'm saying he shouod bs rexast just not for the sequel because that was his movie. Just use whatever foitage of him they got and pass the mantle to shuri for the time being. Then In the third movie which will be years from now they can replace him in sorry but black panther is bigger than Chadwick Bozeman nay he rest in peace but there are more of t'challa and wakanda as stories that can be told especially with the fantastic four on the way.
