One major surprise was the announcement of Oscar victor Mahershala Ali as Blade the vampire hunter, a role played by Wesley Snipes in the 1998 film. Interestingly, Harbour's character in Stranger Things 3 butted heads quite a bit with an ill-fated character named Alexei.
As well as the exciting announcement of Blade, Marvel also confirmed that Natalie Portman is to take up Thor's famous hammer Mjolnir for the fourth film of the Thor saga, which is to be entitled Thor: Love and Thunder. She will be seen sharing the screen space with Chris Hemsworth and Tessa Thompson.
This is the latest news to come from Marvel on what's in store for the studio after it ended a decade of story building with the epic Avengers: Endgame in April.
More than that, the first two Blade films are underrated masterpieces of the superhero canon.
As if all this wasn't enough, Mahershala Ali also took to the stage simply to wear a Blade hat, revealing that the series was indeed returning.

New characters means new actors, and because there's so many big additions, we chose to round up everyone who's joining (or returning to) the Marvel Cinematic Universe in a big new role. But even with a 90 minute plus running time, Kevin Feige and co. didn't have time to offer full details on everything they're cooking up.
We didn't get full reveals of anything else, but we were told in passing that Marvel is working on Black Panther and Captain Marvel sequels, as well as trying to bring Fantastic Four and X-Men into the MCU.
