I'm not sure how "official" this is because it is all shakey and bootleggy. But here is
10 minutes of brutal footage from the upcoming
Piranha 3D.
Alledgedly, this was supposed to be screened at Comic-Con but was cancelled due to the extremely intense R-rated nature of the footage. I'm not sure where they draw the line at things like that or how they police themselves, but there is no denying that the content is pervasively disturbing.
I was on the fence myself, but this may have sold me. It also appears to be taking itself way more seriously than I originally thought it might. The thing that worries me is that there are so many killshots and gore gags here it makes me wonder what is left. Like a bad trailer, I may have seen all the best stuff beforehand.
So be forewarned, it's lengthy and spoilerific. And, of course, very R-rated and NSFW. It's also something that may disappear quickly, as is the nature of second-hand footage like this.
I'm sure this is right in your wheelhouse, Jaws3Dfan. Unless you want to avoid spoilers, enjoy.
