At the annual San Diego Comic-Con this year, Mahershala Ali was announced as being cast to play the supernatural superhero Blade in a future Marvel Cinematic Universe, who also played Cotton Mouth in Marvel's Luke Cage in 2016 (which they say is set in MCU).
This is not the first time something like this has happened, Alfre Woodard who played the role of Miriam Sharpe (the lady who blames Tony for her son's death in battle of Sokovia in Civil War) also played the role of Mariah Dillard in Marvel's Luke Cage.
Now, we all know how they talk about "it's all connected" but is it really?
What does the casting of Ali as Blade implies? Like the Marvel TV shows like Agents of S.H.I.E.L.D. and Marvel-Netflix shows aren't canon to the MCU anymore?
