btw, and i don't necessarily think this will happen, but by the time this movie is in production (if it even gets there, let's be real) the general public could be sick of the Rock. The dude works too damn much. Look at some of the shyt he has coming down the pike. Baywatch, Jumanji, he said there's talk of a spinoff of his Fast character (who the fukk wants that?) then he has the author of Jason Bourne cinematic universe (yea, that's a thing apparently) Doc Savage, and probably 5 other movies i can't recall without looking at his imdb. There's such a thing as oversaturation, it happens to every super famous person at some point, save a few.
is it really that great to lockdown a megastar in the present for something 5 years in the future? ... which then opens up another possibility that they'll try to shoehorn this character into an earlier movie for no reason, b/c once again, they're not good at this game.
