As long as we don't have anymore Ghostbusters in wheelchairs, for the sake of "diversity", I could live with it.
How do you know he can? Frankly, I'm dreading the new Indiana Jones movie. I'm half-expecting Ford to be like Charles Bronson in the last few Death Wish movies, with his stunt double having more screen time than he does. For Ghostbusters, let's stick with animation. No matter how old the original cast may be, they can still do the voices.
