The currently-reigning king of both the quietly macabre and the deafeningly massive, Del Toro's Ghostbusters III is a tantalising prospect because of the possibilities of the ghosts and ghouls he'd be able to create alone. Remember how terrifying and beautiful the creatures from Pan's Labyrinth and Hellboy: The Golden Army were? Well, imagine what you'd get if Sony were to give Guillermo Del Toro a true blockbuster budget akin to Pacific Rim's. Imagine an underground city of ghosts and marvel at why nobody's paid the writer-director to make this movie already. Some might question Del Toro's comedic sensibilities, but both of his Hellboy films had a charming, infectious sense of humour that was surprisingly lacking from Pacific Rim, but nevertheless shows that the director can handle a punchline or two, and he's such a big movie fanboy in general that he certainly wouldn't want to condense Murray and Aykroyd's screentime for the sake of another gorgeous monster. Unfortunately, the director's attached to so many other projects right now, from his upcoming ghostly period piece Crimson Peak and imminent vampire TV show The Strain to his languishing Lovecraft project At The Mountains Of Madness and a million other sequels and reboots in between that by the time he'd manage to get around to working on the damn thing most of the principal actors would either be geriatric or dead...which is probably less of a problem for this franchise than most, actually.
