Possibly (definitely) an offbeat choice, but give us a moment here: just imagine what the director of The Nightmare Before Christmas and Coraline could do with an animated Ghostbusters movie and a budget to match. Hell, he could make his transition to live-action just so that everyone gets the gratification of seeing the leads in the flesh immediately before they're killed (as Bill Murray has previously stated, he's only willing to star in another Ghostbusters movie if he dies in the first twenty minutes) and resurrected as stop-motion ghosts made to haunt the younger protagonists with withering insults, like an undead Statler & Waldorf. Selick blends creepy and silly perfectly in his films and his sensibilities would bring a darker sensibility to the series that we haven't seen before, one that could lead to a bigger interest in the titular ghosts' stories and motivations and flip the central dynamic on its head, as the director did with Nightmare (the heroes in the story all look like monsters). What if the ghosts are the victims after all? It'd be a tough sell - especially if Selick wanted to make a musical, but be honest with yourself about how much you'd love to see a ghostly Bill Murray break into song - but this way Sony would be able to keep costs down if they ended up having more script problems and setbacks and wouldn't end up with a bunch of expensive, unusable footage.
