Help?

Hello.

I came across this making for a monster movie project. I was wondering if these models were hand made or if they were from a site? They seems to be large scale? I was just wondering if someone would know, or have an idea on how these could be made? :confused:

I put a link to the monster clip link below. Warning, models are being crushed.

Thanks!
