The Gist: Back in 2007, Dan Aykroyd knocked up a script in which the Ghostbusters take an inter-dimensional leap into Hell. With a bit of tweaking, there’s no reason why this has to end up on the scrapheap, with Venkman and co. considering themselves “too old for this shit” and training up some new recruits to head into the fiery depths.

Pros: Aykroyd probably has a copy of the script kicking around his attic, so that Christmas 2012 release date may yet be doable.

Cons: Aykroyd’s “Manhellton” moniker for the parallel Manhattan is frankly a bit shit.
