I like Idris Elba, but I don't know about casting the same actor after he's already played someone else in that same universe. They need to give somebody else that shine IMO.
Either way, they need to hire some real comic fans to make a Claremont/Byrne/Austin era X-men movie for this reboot.
On a side note...
Storm/Forge >>>>>>>>> Storm/Black Panther
(I'm all for black people shining but Storm and Panther aren't a very well-written couple IMO.)
Comicbook Cyclops >>>
(The movies dumbed down his character)
Wolverine in his brown and yellow costume > the blue and yellow suit.
Late 70s/early 80s Claremont is the GOAT era. Claremont/Byrne >>>> the 90s.
The 90s cartoon >>>>> the movies.
(First Class was competently made, but the

-ness ruined it for me.)
