Cut the gore
I almost puked when I saw the trailer. Ok, it's supposed to be "extreme" but there's no way any sensible censor authority should allow some of the stuff for public screening. We're a little mild in the east, and we like it that way, the Punjabi-Pakistani cinema notwithstanding.
It would be great if the gore could be toned down in order for the film to be put up for mainstream release. Considering Zibahkhana should break even on DVD sales [international + local] alone, it would only be something positive for the deserted cinema houses and multiplexes. They probably could use some "elite" cinema to bring the "elite" audiences in. Zibaahkhana should do the trick.
And please, someone cut that really corny "Pakistan ki Pehlee Extreme horror film" tag too.
