A few thoughts on this:
1. This has to be better than the low-budget (but still somewhat entertaining in a psychotic kind of way) live-action Hong Kong version of
Wicked City from 1992.
2. The rape stuff
has to be toned down. The original 1987
Wicked City (AKA
Supernatural Beast City) anime didn't quite cross the line into hardcore
hentai, but it came pretty close (sort of the like the director's other famous work,
Ninja Scroll). The part where the fingernail blade heroine (whose name I forget) is captured and gang-raped by the demon men just ain't gonna fly outside of anime fetishland.
That being said, the spider-demon **** with the toothy cootchy does need to be in there.
3. The Wicked City manga and anime were
heavily influenced by John Carpenter's
The Thing. There are going to need to be some tweaks to keep horror/monster fans from getting a "been there, done that" feeling.
Those are my main concerns, now bring on the movie.
