You could remake Ghostbusters with four male actors, and it would still suck. The original movie was great because of the people in it. They are not in this movie, therefore, this movie will suck.
Just as the Magnificent Seven remake will also suck. It does not have Yul Brynner, Steve McQueen, Charles Bronson or James Coburn. It doesn’t matter who they got to be in the remake, because those guys are gone, therefore the remake will suck.
I can not figure out why anybody greenlighted either of these films. They are both doomed from the git-go.
Heck even Ghostbusters II was lame and had most(?) of the same cast.
So did the awful "Ghostbusters 2." The original was a lightning-in-a-bottle kind of movie.
The Magnificent Seven was good because of the cast, but looking deeper it was a lesser copy of Seven Samurai, that only had one real star, Mifune.
I think you could do a Magnificent Seven without the original cast, but the writing and production would have to be much better to compensate.
The new True Grit by the Coen bros for instance was better than the John Wayne version, because they did justice to the style and language of the original novel.
