Nochnoi Dozor. That was an awesome film. Then the end of Dnevnoi Dozor sucked balls, and rumour has it that Fox Searchlight stepped in for the third release and have demanded that it be made in America, with American producers, engineers, camerapeople, and so forth.
If I had created this, I would NEVER let them fuck this so royally as they're setting to do. If they recast it too, and lose Khabensky and all the others, then I'll be forced to annihilate all their firstborn sons. So it is written, so shall it be done.

Then we get MySpace and Facebook, which held large elements of my initial proposal.

Less things than characters -- I have a series of comics that I've been working on since I was nineteen years old, in which various characters were stand-ins for universal characteristics. In my case, "Death" was a teenage goth girl and "Brutality" was a ghost who looked like Lee Marvin. Neil Gaiman and Garth Ennis, needless to say, have totally fucked my shit up. (Between Warren Ellis and the Japanese anime series Dennou Coil, my postulation of modern computing has been totally compromised as well, but fuck 'em, I'm using it anyway.)
