Alien 3 (Direct follow up to Aliens, missing out all the other rubbish that followed)
Ripley, Hicks, aliens, marines, guns, more guns,
Earth and even more aliens. Complete and utter carnage.

Rated at least 18, though perhaps a new classification would be required.
The Thing 2
The Thing got loose and is rapidly infesting the whole planet. A Sombrero wearing Kurt Russell will be our only hope. This film will be championed by Mark Kermode, mainly because it will feature the most mind bending and disgusting special effects that have been seen on film. The Daily Mail may also give it away as a free DVD offer. Possibly banned by the BBFC soon after.
The Silmarillion
Nine hours of unremitting misery, despair, doom and surfing Elves. The extended DVD versions will be much longer, feature added hopelessness and maybe some incest.
