Why does everything have to be a damn
FRANCHISE? It was a classic movie made 25 years ago, with one failed, mostly forgotten sequel to its name. I don't call that a franchise, especially one that so desperately needs to be resurrected.
Snake is not Batman, Spider-Man or Bond. Those are characters that existed before and outside of their movies; the actors who portray them are merely custodians of the character.
Snake is Kurt. Kurt is Snake.
You know what it's more comparable to?
Evil Dead. Or hell, even Jay & Silent Bob.
Ash is Bruce. Bruce is Ash.
Should someone other than Jason Mewes and Kevin Smith play Jay and Silent Bob if, for some ungodly reason, some tool decides to remake Clerks in 2067?
They are characters created by a director/actor duo that exist only in the context of that union.
Maybe some day, they'll remake ROCKY. And maybe on that day, everyone will rally behind the actor of the week to play Balboa, because he just had a hit 3 days ago (forgetting he bombed out as both the Phantom and Dracula a mere few years earlier).
Jesus Christ on a Cross, dying for our sins.
