No but really, are you serious? ;)
I'm not serious. It was my first impression so I had to post it.
I knew it but I'm just asking anyway. She doesn't even look like any of the characters! :D Gia? Nope. Steffi? Yeah, sure... Victoria? No way! Well, maybe a little bit of Girl 6 (enormous eyes).
I was thinking however if this sort of mystification would hold and if, then for how long? That's a big reality check - in order to make a 30 second animation of a model just moving around it would probably take some 30 minutes of your precious time. However, how long would that take for you to create a 30 MINUTE documentary with a fake person NOT ONLY moving but also SPEAKING which would require LIP SYNCHRONIZATION. :D I know some geeks would probably be happy to animate even nose hair but this takes time and a lot of it. I think such a detailed animation (including hair, lip sync, eyelids, hand gesture) would take, as I see it, 5 hrs work for each 30 seconds of the footage. If documentary lasts for 20 minutes and a half that would require 205 hrs! That's a week's time. Add some complimentary coffee breaks, and meals (if any!) and you are comfortably sitting at an eleven day project.
Don't forget however that your hoax needs to live too, so whether you want it or not you need to make some regular video-posts, say, 15 minutes each. How much work would that require according to you? MUCH. ;D
This is sad. Incredibly. :(
