In 2002, New Line Cinema grabbed a screenplay by the writer of Ocean's Eleven about a clairvoyant doctor who helps the FBI catch a serial killer and rewrote it as a sequel for Se7en, replacing the protagonist with Morgan Freeman's character from the first film. It's the exact same character, only this time around he has psychic powers (or maybe he had them all along but just didn't mention it in the first one).
"Because eat me, that's why."
This script was at one point sent to David Fincher, who said "it didn't make a lot of sense" and later commented that he would rather have cigarettes put out in his eye than do Ei8ht. So that's probably a no for him. We're pretty sure Brad Pitt would have sided with his pal Fincher ... but you never know about Morgan Freeman.
