If theres one movie in the entire universe that doesnt lend itself to a follow-up, it would be David Finchers Seven. Ending with Brad Pitt and Morgan Freeman finding a nasty surprise in a cardboard box, it certainly didnt seem to be setting up future adventures. Since it was a massive success obviously the studio had to try to come up with something; so they optioned an original script about a psychic doctor hunting down a serial killer and reconfigured it to be a Seven sequel. The working title was Ei8ht and it would have seen Morgan Freemans Somerset become somehow psychic and chasing a new killer. Brad Pitts Mills wouldnt have featured, with the explanation being that his character ended up in a mental hospital. The movie never got made as the inherent stupidity of the concept put everyone off, with Fincher being quoted as saying I would be less interested in that than I would in having cigarettes put out in my eyes. The original script eventually became Solace, with Anthony Hopkins playing the psychic doctor and Colin Farrell as the killer; if you havent heard of it, theres a good reason.
