Well, vegans are usually pretty blown in the head, if they had control, the world would grind to a halt in a week.
It's not like the film industry has its own slaughterhouses or crops of life-stock to make gelatine, it simply utilize the byproducts from the meat-industry, which is a good way to be eco-friendly, as long as people eat meat.
There are also claims that the gelatine is made from whale-meat, which is pure bullcrap, but it just shows how big lies vegans like to make, to save their pretty little animals.
Gladly, a vegan would not last more than 2 weeks, tops, in the wild. This is a simple way to prove that the whole fundamental ideology of theirs, is as close to bull**** that you can possibly get.
