If you know what happened to the acting Legend Chadwick Boseman, then you will already know that 1. The director Ryan Coogler had a heck of a task before him..and 2. Marvel's Kevin Feige had a heck of a choice to make. For those who do not know, Chadwick Boseman acted and starred as the titular character Black Panther whilst battling stage 4 Cancer. Chadwick told nobody of this and carried out his acting roles in Marvel movies and other movies for years before succumbing to the disease. Chadwick was such a great actor who left us with an iconic portrayal of the character that Marvel have decided NOT to recast T'Challa. Whislt I have heard some rumours going forward for the movie, we will have to see how this movie pans out. There will be some who would like to see someone recast as T'Challa and there are some who will say not to have him recast and let Shuri, T'Challa's sister played by Letitia Wright to play Black Panther like in the comics. Chadwick was a great person, so filling his shoes will be a lot of pressure for the new actor in this role.
This trailer is beautiful. It seems to pay tribute to Chadwick as well as T'Challa. All eyes are on this movie and on Marvel on how they will execute his passing in real life and possibly in the movie, how does this play within the main story. This teaser trailer seems show Wakanda being swept up by the ocean, caused by Namor the Submariner (wild guess). Whilst we are not entire clear what is actually happening here in this, it does seem that Shuri, will take up the mantle of Black Panther, even if for a short time and a war with Atlantis breaks out. Let's wait for the first official trailer where more information will be given to us. But one thing is for sure, this WILL BE a very emotional movie for everyone who loved Chadwick as T'Challa.
