Well, if you want a character to wave for a few seconds, wouldn’t it be quicker to have a person wave in front of a camera than to draw and paint 120 pictures of a person in different “waving” positions (well, nobody would really do that for TV, they’d just draw the person and the arm separately, and then draw a few pictures of the arm going in one direction, film that, then loop it to get a waving effect, but you get the idea)?
It should, but they still say it takes six months.
