Even with computers, it takes me about 2 to 4 months to just do about five minutes worth of animation. Early hand drawn animation was a process that involved just as many people as it does today. There were initial artist that did the main work, but there were other artists that did the "in-betweening" to get enough frames to film.
Today, computers can do the in-betweening, which helps a lot, but every other aspect of the production, story, writing, pre-production design, sound, effects, etc, still takes as much time as it always did, and that's just 2D, which I do. 3D is even more complicated. Watch a movie like "Shreck" and watch the credits, you can se the hundreds of people and different companies that work to make the film.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
